Lethal Weapon is a tetralogy of American action movies/comedies directed by Richard Donner and starring Mel Gibson and Danny Glover as a pair of mismatched detectives in the LAPD. The first movie effectively defined the entire Buddy Cop Show genre. The unbalanced, unhinged Riggs was contrasted with calmer, stricter family man Murtaugh. All four films were directed by Richard Donner.In Lethal Weapon (1987), Glover is playing Roger Murtaugh, the strict cop that plays by the rules, and worries about getting too old (for this shit). He is partnered with Martin Riggs, a suicidal badass despairing over the death of his wife. Riggs is well versed with both martial arts and gun play and added to his berserker tendencies makes him a candidate to be registered as a lethal weapon. They start tracking down a major drug dealer who has ties within the force.In Lethal Weapon 2 (1989), they received a comedy sidekick played by Joe Pesci as a witness and insider to the new bad guys. The Big Bad of the movie was Arjen Rudd, a South African diplomat using diplomatic immunity to hide behind drug smuggling. As it turned out, he was responsible for the death of Mrs. Riggs.In Lethal Weapon 3 (1992), Riggs finds a new Love Interest in Lorna Cole (Rene Russo), a fellow cop who is as tough and crazy as he is. She helps them to investigate a rogue officer who's been selling specialized armor piercing "cop killer" bullets to the mob and onto the streets. Looming over Murtaugh's head is his upcoming retirement and trying to figure out his life as a cop and what it will be like after retirement.In the final installment, Lethal Weapon 4 (1998), Lorna is pregnant with Riggs' baby and both he and Murtaugh are contemplating the implications of growing older. Meanwhile, Riggs and Murtaugh receive a brash younger detective named Lee Butters (Chris Rock) and are dealing with Chinese Triads when they uncover a boatload of illegal immigrants. The Dragon (In Chief) /Big Bad of this group is Wah Sing Ku, played by Jet Li, by whom Riggs finds himself entirely outmatched.Each movie played out like a cross between the typical cop show and Indiana Jones, with spectacular stunts at a breakneck pace while following a chain of evidence.Now has a character sheet
By the end of Lethal Weapon 3, he jokes about going back to cigarettes to deal with his "dog biscuit problem".
The Alleged Car: Murtaugh's wife's station wagon turns into this over the course of the second film.
All Girls Want Bad Boys: The first movie, when Riggs has dinner with Murtaugh's family, the oldest daughter is making eyes at Riggs, and the attraction seems to come from this, especially when Riggs sides with her in a father-daughter fight over her marijuana use.
As a result, Murtaugh is paranoid about his daughter and Riggs during the entire freaking series!!!
Rika in the second film, Lorna from 3 onward.
For that matter, presumably the late Mrs. Riggs.
Unfortunately for Murtaugh, another detective named Lee Butters got to her while he was distracted.
The Artifact: In the second film Leo is introduced as a key witness and much of the plot revolves around protecting him; for the rest of the series he is reduced to the Plucky Comic Relief, though he still briefly helps out in both cases.
Ate His Gun: Riggs is outright suicidal in the first film. In an early scene, he actually puts his gun in his mouth, but doesn't shoot.
Avenging the Villain: Near the end of the fourth film Wah Sing Ku is attempting to flee Riggs and Murtaugh with his brother, all the other villains having been killed. When Murtaugh shoots Ku's brother while aiming for Ku himself, Ku sticks around and tries to kill Riggs and Murtaugh in revenge. Riggs then shoots Ku underwater after they fall off a pier while fighting.
Badass Boast: Riggs has several throughout, but his Defining Character Moment in the first film really hits this trope hard: "When I was 19, I did a guy in Laos from a thousand yards out. It was a rifle shot in high wind. Maybe eight or even ten guys in the world could have made that shot. It's the only thing I was ever good at."
Bash Brothers: Riggs and Murtaugh don't embody this trope until the final fight against Ku in the fourth movie.
Bizarre and Improbable Ballistics: The "cop-killer" bullets that are the basis of the plot in III seem a tad inconsistent in their destruction; they are so powerful that they can not only punch through two sides of a steel drum AND a vest worn by Billy (killing him), they can even penetrate a bulldozer blade and its engine block to kill the Big Bad! However, Lorna's two bulletproof vests stop them dead. Somehow.
Bombproof Appliance: A bathtub. The MythBusters eventually tested this as in the scene, and aside from the detonation method (which actually took longer to go off), it all worked exactly as advertised.
Bond One-Liner: From the second film: "Nailed 'em both." Also, the one in the next entry.
Bond Villain Stupidity: Invoked several times in the second film, in which the villains have numerous opportunities to dispose of Riggs and Murtaugh and don't.
Boom, Headshot: Roger's signature maneuver, done once a film, after rolling his head from side-to-side to crack his neck.
How Roger takes care of the driver of General McAllister's car.
Bowdlerize: The films are played quite frequently on TNT and TBS, which are infamous for censoring language in films. For someone who's familiar with the theatrical version of the first film, watching it on one of these networks can be quite hilarious for that very reason. Unfortunately, sometimes the censorship seems unnecessary and arbitrary— like when they cut out Riggs punching the guy on the hood of the car in Lethal Weapon 3 after asking if he was all right.
Also, in Britain the theatrical release of Lethal Weapon 2 cuts the scene where Riggs kills two of the villains who drowned Rika after he uses his Houdini impression to escape the same fate.
Brick Joke: Chekhov's Nailgun has a longer run than you'd expect. In the third film, it reminds Murtaugh, who is trying to sell his house, that he forgot to get permits to repair his blown-up house!
After Murtaugh's daughter appears in a condom advertisement, Murtaugh bemoans how his police colleagues will be planting condoms wherever he goes. That night Murtaugh and his family are attacked in their home and no-one is interested in playing jokes on him...until later on in the movie when Murtaugh shoos away some cops crowding around his desk only to find they've planted a 'rubber tree' there. Even Murtaugh can't help breaking down in laughter.
Call Forward: The musical riffs we first hear in the original film are later used in Sting and Eric Clapton's "It's Probably Me", the hit single from the third film.
Car Cushion: The first film opens with Amanda Hunsacker committing suicide by throwing herself off a balcony and onto a parked car below.
Career Building Blunder: After the third film, where Riggs and Murtaugh were busted down to patrolmen for messing with the bomb squad's job (and blowing up a building), the fourth film has the department unable to get their insurance renewed due to the propensity of the duo causing catastrophic damage in their escapades. But since they can't be demoted off the streets, the department decides to promote them, fully two steps, bypassing Lieutenant and making them both Captains, at least until the insurance is renewed, in an attempt to get them off the streets. It does not work.
The SWAT team arriving about a minute or so after Riggs shoots the playground sniper near the beginning of the first film.
This scene was (wisely) cut from the theatrical release and reinserted for the Director's Cut DVD.
Subverted in the third film, where Riggs argues that the bomb squad never gets here on time!"; they meddle with the bomb, it goes off, a massive building is levelled... and the bomb squad immediately pulls up, having arrived in plenty of time to deal with the bomb had Riggs not interfered.
Chekhov'sDislocated Shoulder which keeps coming back. In the second film, Riggs voluntarily dislocating his shoulder to get out of a straitjacket on a bet is used comedically to show how nuts he is. But when the villains try to kill him by putting him in a straitjacket and tossing him into a river, he's able to get out of it, swim up to the surface, and take out two of them.
During the fight with Wah Sing Ku, after he dislocated Riggs' shoulder, Riggs gives him a short but brutal No-Holds-Barred Beatdown.
He also has to reset his shoulder twice in the third film, though not under such mortal circumstances. At one point, he slides himself into a pole to do so on the fly.
A literal one is in the third film, with the machine gun loaded with "cop killers." Sold to Tyrone by Travis, who then sells it to Darryl, it is taken by Murtaugh when he kills Darryl. Later he uses it against the bad guys and finally tosses it to Riggs - who uses it to kill Travis.
Chekhov's Skill: Riggs' ability to dislocate and reset his shoulder was used as a gag early in the second movie, only to become important to Riggs escaping a death trap. Similarly, in the third movie Riggs taught Murtaugh a basic defensive kick which was made into a prank with Murtaugh kicking over a water cooler, which Murtaugh used instinctively in the climax.
Cold-Blooded Torture: Riggs and Murtaugh are both subjected to this in the first film, as the bad guys try to find out from them what the police know. It doesn't work, because the cops don't know much of anything, and because Riggs is able to escape from Endo and go on a rampage.
Combat Pragmatist: Despite being a highly trained martial artist, Riggs isn't against groin attacks, unsing improvised weaponry, dropping a crate on a man, or killing him with a machine gun when it becomes clear he's not going to win a fist fight.
Lorna Cole isn't above using groin attacks either as evidenced in Lethal Weapon 3 when she grabs a man by his junk and pulls it upward rather...painfully.
Murtaugh: When are you gonna learn you can't solve every problem with your fists?
Riggs: Well, I couldn't use my gun; there was a crowd.
Continuity Nod: Many scenes from previous films are mentioned throughout the series. Perhaps the funniest continuity nod is in Lethal Weapon 3, in which Leo serves a realty agent trying to help Roger sell his house. Because of full disclosure issues, when the prospective buyers mention that they love the picture window, he says it's recently been replaced because a drug dealer crashed his car through it and shot the entire place up. (A reference to the first film, but see below). Then he has to mention the damage that happened in Lethal Weapon 2:
Leo Getz: The bathroom upstairs has been completely remodeled due to unexpected bomb damage.
Granted the thing with the picture window happened before Leo knew Riggs and Murtaugh, and therefore he may have been told a different story from what really happened— but it was the good guys who actually drove the car through the window in the first film.
Fridge Brilliance: Murtaugh would probably have spun the story that way to the insurance company.
Also, Riggs and Lorna flirting in the third film, Riggs mentions a 'whole family of .44s on the back' from where Arjen Rudd shot him at the end of LW2 and he also mentions the knife Vorstedt got him with in the leg at the climax.
Crazy-Prepared: Not so much crazy as it was clever, but Lorna managed to survive a potentially fatal cop-killer bullet wound by wearing twoBullet Proof Vests just in case.
Creative Closing Credits: The fourth movie has pictures of the cast and crew with "Why Can't We Be Friends" in the background.
The Danza: Delores Hall plays Delores in Lethal Weapon 3.
Darker and Edgier: Although all of the movies contain a fair amount of humour and over-the-top scenarios, the first movie is generally a bit darker and more grim than the more cartoon-like later movies, focussing heavily on Riggs' suicidal tendencies and framing his out-of-control nature as borderline psychotic.
Did Not Die That Way: Martin's wife was said to have been killed in a car accident. Turns out in Lethal Weapon 2 that the "accident" in question was a deliberate hit-and-run by that movie's Big Bad that was meant to kill Riggs himself but got her instead.
Diplomatic Impunity: Arjen Rudd claims diplomatic immunity to make the heroes back off in the second movie. (Although in fact, he was only a consular officer, and they get a lower grade of immunity - unless he had some other official status as well, he could have been searched provided proper procedures were followed.)
For extra ballsiness, at one point he does this while SHOOTING at Riggs.
The Dragon: Typically opposing Riggs. Mr. Joshua in the first, Pieter in the second.
Dragon Their Feet: In the first film, while General McAllister was barbecuing his nuts on Hollywood Boulevard, Mr. Joshua went to Murtaugh's house to go after Roger's family. But there was "nobody here but us good guys".
Driven to Suicide: The first film opens with one, as young Amanda jumps off a balcony.
"El Niņo" Is Spanish for "The Niņo": In the fourth film, when Riggs, Murtaugh, and Butters seek to question Uncle Benny at a dentist's office, they give him a dose of laughing gas to make him more complacent, except they give him too much gas, making him way too aloof and carefree to be very helpful. His one clue as to the location of the Hongs is "Yao Mihn Bi". When asked what that means, Uncle Benny explains, "'Yao Mihn Bi' means... 'Yao Mihn Bi'."
Embarrassing Middle Name: While interrogating one of Jack Travis's henchmen, Riggs reads out the name on the man's driver's license: Hubert Bartholomew Smith.
Lorna (impressed): Bartholomew!
Even Evil Has Standards: Gangster Tyrone in the third movie is visibly disgusted at Jack Travis's disposing of a rebellious mook by burying him alive in wet cement.
Foreshadowing: In the first film, there's a magnet on the Murtaughs' refrigerator that says something to the effect of "End apartheid in South Africa." Guess who the villains of the second film are?
Four Temperament Ensemble: The main bad guys in each of the films: General Mcallister is phlegmatic, Arjen Rudd is sanguine, Jack Travis is choleric and Wah Sing Ku is melancholic.
From the Mouths of Babes: The six-year-old witnesses to Dixie's house being bombed in the first film. "You're gonna bust Dixie! You're gonna bust Dixie!" Later, after the bombing: "My Mom says policemen shoot black people!" Mel Gibson looked like he was legitimately cracking up in that scene.
Genre Savvy: Subverted hilariously. In the third film, Riggs insists that he and Murtaugh go into the parking garage to try and defuse the bomb because "the bomb squad never gets there on time", as if that's a truism he's learned from experience or possibly from watching too many movies. After Riggs screws it up ("GRAB THE CAT!"), the bomb squad arrives seconds later. They would have had more than enough time to defuse the bomb if not for Riggs. They give him a sarcastic round of applause, too.
Played straight by Murtaugh in the same scene, who argues against messing with the bomb because he's only eight days from retirement and he doesn't want to do anything stupid.
Played straight in the first film by the bus driver whose car collides with McAllister's. He quickly backs the bus back several yards, just in case the car were to explode. Smart man.
Gilligan Cut: Murtaugh, stuck on the toilet, begs Riggs to keep his call to the bomb squad discreet. Guess what happens instead?
Give Me a Sword: Murtaugh tosses Riggs a nightstick in the fight with Mr. Joshua near the end of the first film, in response to the latter using a pole against him.
Good Cop/Bad Cop: Almost immediately after meeting Leo Getz in Lethal Weapon 2, Riggs tells him to shut up. Getz says, "Oh, I get it— good cop, bad cop." Then Murtaugh also tells him to shut up. "Okay... bad cop, bad cop."
Good Is Not Dumb: After Riggs is blown through a window by a shotgun in the first film (he was wearing his bulletproof vest, so he didn't die), he points out to Murtaugh that now the police have the advantage, because the bad guys think Riggs is dead. Sure enough, Mr. Joshua calls the police station for information about the shooting, claiming to be a news reporter. The officer who picks up confirms that Riggs is dead, and it never occurs to McAllister and Joshua that the police could be deceiving them.
Goofy Print Underwear: Murtaugh from 4; when directed by Riggs to strip to his boxer shorts to distract a madman wielding a flamethrower, Riggs asks with a laugh "Are those little hearts?"
Guns Do Not Work That Way: The idea that "cop killer" bullets are an option for the submachine guns seen in part 3 is nonsense. By the time you've juiced up, say, a regular 9mm with a sufficiently hardened bullet (just being pointy won't cut it) and enough propellant to punch through thick steel or kevlar, it's very likely going to explode that MAC10 you were hoping to feed it into. Best to just chalk the whole mess up to Rule Of Cool.
Hair-Trigger Temper: Averted; Joe Pesci is famous for such roles played scarily straight but his character Leo Getz is harmless. In fact, he plays a fall guy. He's still liable to fly off the handle at the slightest provocation, but everyone's more than aware it's all bluster and Riggs and Murtagh are more than willing to tell him to shut up.
Heavily Armored Mook: The flamethrower and machinegun wielding lunatic at the start of the fourth movie.
Heroic BSOD: In the second film, when The Dragon reveals he killed Riggs' wife Victoria, and then he kills Rika, too.
In the third film, Murtaugh goes on a drinking binge after he was forced to kill a teenager (who was a friend of his son's). In a Role Reversal, Riggs has to play the sane man in the entire episode.
He's Back: And when he recovers from it, and is told by said teenager's mourning parents to "get the man who put the gun in [their] son's hands" ... oh boy, is he back.
The fact that General Mc Allister has explosives in his car enables Roger to kill him (by killing his driver, causing an overturned-vehicle crash) in the first film.
Riggs stabs Vorstedt with his own knife in the second film.
Riggs kills Travis with a gun modified with cop-killer bullets (which Travis helped put back on the streets to begin with) in the third film.
And it is in fact the very same gun used by the boy Murtaugh shot. Which Travis stole from LAPD impound and sold to the boy in the first place.
A more comedic example would be in the fourth film when Riggs wants to ask the psychiatrist for legitimate advice regarding his intent to marry Lorna, but his years of mocking her makes her instantly go on the defensive and assume he's trying to punk her again.
Honor Before Reason: In the climax of the fourth film, Riggs and Murtaugh had successfully thwarted the bad guys plans. But they killed Ku's brother, leaving him seriously pissed. They had more than enough time to make their exit and stay away from Ku's wrath and even begin to walk the other way, talking about coming back with a howitzer or something like it. But Riggs started musing about Ku's crazy gun dismantling trick he pulled earlier in the film and they realized they had to face him to end it.
Hot Pursuit: Played straight to the point of parody to the point of subversion back around to straight, all in record time.
Idiot Ball: "Wow, good thing we escaped your evil employers who just tried to kill us, Miss Van den Haas. Now let's drop you off at your apartment, where they know you live, without any police protection!" *hands ball to her* "Hey, great idea, Officer Riggs!"
Also Arjen Rudd in the second movie. Near the end of the movie he starts to shoot at the policemen and claims diplomatic immunity that can protect one from being arrested but not, you know, from being shot in self defense. Had he refrained from shooting, the protagonists could have done nothing without provoking a major international incident.
Improbable Aiming Skills: Riggs pulls off some incredible shots. Sure, Murtaugh has his share, but Riggs was breast-fed on this trope. The sniper in the school, being able to shoot a smiley-face on the firing range, being able to successfully hit a helicopter God knows how many yards away, etc. all with a pistol. And then picking off Shadow Company mooks like flies. And that's just the first film.
In part 2, how about fatally shooting the pilot of a helicopter in the dark from about 100 yards away. With a pistol.
The "have-a-nice-day" moment in the first film. Murtaugh lampshades Riggs' improbable aiming skills perfectly:
Murtaugh[re: Riggs' gun]: You sleep with that thing under your pillow or something?
When Roger rolls his head from side-to-side and cracks his neck, watch out.
As for Murtaugh, he pulls off an excellent shot to kill the Big Bad of both parts 1 and 2. In part 1, he shoots the driver of a car coming right at him, and then gets out of the way as the out-of-control car goes flying onto Hollywood Boulevard and smashes into a bus. And in part 2, he revokes Rudd's diplomatic immunity with a damned impressive head shot.
In fact, in part 2, Murtaugh not only scores a head shot on Rudd, but the bullet goes through Rudd's photo on his diplomat ID. Making it, in fact, two headshots with one bullet.Yeah.
Funny enough, it's averted completely in the third film—where Murtaugh has to ventilate a shed to get Darryl, then uses a machine gun on Jack Travis—and deconstructed in the fourth, where Wah dodges the shot—only for it to hit and kill his brother.
Deconstructed in the fourth movie, when his age takes away the 'lightning part'. He's still faster and a better fighter than Murtaugh, but his age showing in his fighting prowess is a major plot-point.
Make It Look Like An Accident: Parodied in the third film. After Riggs and Murtaugh are busted down to patrolmen, they catch a guy jaywalking; when they say they're gonna cite him for it, the jaywalker is apoplectic. "You've got people actually committing crimes in this city, and you're busting me for crossing the street?" Eventually, he gets on Riggs' nerves to the point where he's about to pull his gun on him. "Lemme shoot him, Roger! We can make it look like suicide!" After the jaywalker takes off on Roger's advice ("Get out of here before my partner kills you! No, not that way, the other way!"), Riggs and Murtaugh both laugh their asses off - they were only having a little fun with the guy, apparently.
But played painfully straight in the second film when Vorstedt reveals that Riggs' wife's death was not an accident as it appeared and was ruled; Vorstedt sabotaged the brakes to make her car go off the road, as he was trying to kill Riggs himself (who was not in the car).
Mauve Shirt: All the new detectives introduced in the second movie.
The 22-year-old cop, Edwards, who's the butt of jokes at his expense about his age and height throughout the third film, and takes it all with good-natured, innocent charm. He ends up dead at the hands of Jack Travis.
Meaningful Name: Leo tries to make this work for him. (And mostly just ends up annoying people.)
Leo Getz: My name's Leo Getz. Whatever you want, Leo gets. Get it?!
No Celebrities Were Harmed: The hockey teams playing at the Forum in Lethal Weapon 3 were obviously meant to be the Los Angeles Kings and the Toronto Maple Leafs. The colors are just about identical. Look closely enough at the right time, though, and you'll see they're wearing generic uniforms.
If you pay attention, the film actually features stock footage of the Los Angeles Kings and the Toronto Maple Leafs. They apparently couldn't get rights to use at least real NHL uniforms for the scenes they filmed.
Also in the fourth film with Wah Sing Ku who is younger than both Riggs and Murtaugh and very skilled in a deadly form of martial arts.
One-Man Army: Riggs for the first three films, untl his age finally catches up to him in 4. In all fairness, the only guy he has trouble with in 4 is Jet Li's character.
Outranking Your Job: The fourth film has Riggs and Murtaugh both promoted to captain, but the promotions seem to carry no real weight. Neither is assigned any subordinates or additional responsibilities, and aside from Riggs occasionally announcing, "This is your Captain speaking!" to colleagues, both continue to chase criminals as if they were sergeants - this though the whole point of promoting them was to get them out of the field.
Overly Long Gag: The target takes a long time to get to the end of the range, and a long time to come back.
Papa Wolf: Murtaugh is fiercely protective of his family, but particularly his daughter Rianne. He even punches Riggs right in the face (and overboard) after Riggs says "I think I may have slept with someone I shouldn't have," leading Murtaugh to assume he was talking about Rianne. He was talking about Lorna. Granted, he was drunk at the time.
This is the culmination of three films worth of tension. Murtaugh has always been protective of Rianne, and has worried that Riggs might "go for her".
Joshua:[while jacking a car] Mind if I test-drive your Audi?
Pre-Mortem One-Liner: Non-verbal version; after putting a bomb in Murtaugh's toilet, the bad guys wrote "boom" on the toiler paper.
Private Military Contractors: One of the most evil examples in film: the General and Joshua's heroin network is staffed and run almost exclusively by former Special Forces members who are now just in it for the money. The novelization expands it even more: they also employ Irish, Arabs, Germans, Russians, South Africans, Israelis...
The Purge: The villain in Lethal Weapon 2 does this to the LAPD detectives investigating him, with Riggs and Murtaugh the only survivors.
Reality Is Unrealistic: The Mythbusters tested the scene in the second film where Riggs and Murtaugh survive the toilet bomb by diving into the tub with a bomb blanket. The method would have worked, however, it was found that spraying the bomb with nitrogen would have given the characters a full fifteen minutes to walk out of the house, and diving into the tub wasn't necessary.
Redemption Quest: The entire series is one for Riggs. Murtaugh had his in the third movie after killing a teenager in self-defence.
Refuge in Audacity: Riggs with the suicide jumper in the first film. He was crazier than the jumper.
Martin Riggs:"DO YOU REALLY WANNA JUMP? Do you WANNA? Alright, then, let's do it!"
Riggs is this trope. His signal for Murtaugh to go into the stilt house and start shooting the bad guys is to use his pickup truck to start bringing the whole place down.
Murtaugh: Hey... what's your signal?
Riggs: You'll know it when it happens.
Murtaugh:[sighs] Somehow, I think I will know.
In the third film, Riggs follows Travis out of the subway station by riding on the front of the subway car.
Retirony: Subverted. Early on in Lethal Weapon 3, Murtaugh's wife shoves a bulletproof vest on him, to make sure he always wears it.
Roger Murtaugh: She loves me.
Roaring Rampage of Revenge: Riggs in the second movie, when he finds out that the South Africans killed his wife and his current girlfriend. Good thing Murtaugh was there...
Not quite as vicious, but when Murtaugh returns after Darryl's funeral in the third movie, he goes person-to-person shaking people down to trace his gun. At the first one's house, the home of one of Darryl's homeys, he rants about how gang-banging is tantamount to self-genocide for their race.
Also Getz has a different job in every movie (an accountant in II, a real estate agent in III, and a private investigator in IV).
In the second film, Riggs and Murtaugh are always telling Leo to stay in the car, which he almost always ignores. The one time he does what he's told, two bad guys commandeer the vehicle and kidnap him.
Riggs: Wait for my signal, then just go in and shoot those fuckers.
Shooting Gallery: In the first movie, recently-teamed partners Riggs and Murtaugh are trying to one-up each other on the range. Murtaugh, annoyed at Rigg's tight bullethole group, sends a target further down the range and puts a single bullet through its 'head'. Riggs then sends his target all the way downrange, and shoots a smiley face in the head zone.
Stealth Pun: In the second film, when Murtaugh and Riggs are sitting in the bathroom and Roger is worried he's going to die on the toilet. After Riggs tells him that guys like him don't die on toilets, he adds:
Riggs: Besides, I'm here, and I have no plans on going right now.
The Stinger: Complimenting the scene in Genre Savvy, Riggs and Murtaugh arrive at a building where a bomb had been discovered. They discuss again or not to go in... and just as they stop at the building, it explodes and both leave as Riggs states "I hope nobody saw us".
Stuffed In The Fridge: The original plan for Rika in the second movie was for her to survive and attend the Thanksgiving party at Murtaugh's house with Riggs. Instead, she was killed off just so Riggs would be properly "motivated" for the rest of the movie.
Super Speed: In the 4th movie they had to get Jet Li to slow his fight scenes down because he was too fast for the actors to react to and the camera to catch on film.
Survival Mantra: "We're not too old for this shit... we're not too old for this shit..."
Suspiciously Specific Denial: In Lethal Weapon 3, Riggs gets ahold of one of Jack Travis' flunkies at the garage in which he works, asking him "where's your buddy Travis?" After Lorna is waylaid by five other guys (and beats the crap out of them) while Riggs, Murtaugh and the original suspect watch, Riggs again asks the suspect where Travis is. "I told you, I don't know a Jack Travis." "I didn't say his name was Jack."
Riggs: You better start telling me more than jack shit.
Unusually Uninteresting Sight: In the first film: When Riggs, Murtaugh and Lianne escape from the boiler room, they make their way to the main room of a nightclub. A guy holding a gun turns to face them and Riggs shoots and kills him almost instantly. It's very loud. No one seems to notice. He kills two more people in the nightclub, and no one reacts until the third kill.
Earlier in the first film, this is averted when Hunsacker screams at Murtaugh to "KILL THEM! JUST KILL THEM!" Several people in the background briefly look in his direction.
Villainous Valour: Only Wah Sing Ku is able to disasemble a Beretta in 5 seconds with his own bare hands and then knocking off Riggs and Murtaugh who are older and taller than him. In the final showdown he once again manages to handle them even if they are two vs one.
Wire Dilemma: Occurs in the third movie... and the bomb goes off.
Why Don't You Just Shoot Him?: At one point in the second film, the Big Bad's Dragon and two Mooks attempt to kill Riggs by putting him in a straightjacket and throwing him in the ocean when presumably they could have just shot him.
The Worf Effect: Done interestingly in the fourth film. Riggs realizes his age when the primary henchmen on the boat handily kicked his ass. But Ku ends up dispatching that henchmen with embarrassing little effort, proving that he will be quite an enemy to beat.
You Have Failed Me: In the second movie, after Rudd's henchman Hans loses a million dollars worth of gold Krugerrands, Rudd has him executed.
In the third film, the Big Bad, Jack Travis, does this to both guys who attempted the armored car robbery, because they were "going into business for themselves" and running the risk of screwing up the entire operation. He has one of them drowned in cement and left to be paved over, and then goes into an interrogation room and shoots the other one in the head.
You Just Ruined the Shot: Riggs tries to save Rianne from what he thinks is a hostage situation, but turns out to be a scene in the movie she's in.
