Ambiguously Gay: The director of the second movie has stated that Frank is gay, but it's only written in on the subtext level. Inspector Tarconi's description of his relationship with Frank makes them sound like a gay couple, and Frank turns down the advances of Audrey Billings, but that could just as easily be because she's tipsy, emotionally vulnerable, and married to his employer. It's also contradicted by the events of the other movies, where he sleeps with women and (in 3) says he's not gay.
Artistic License:Physics: Can a set of bicycle pedals strapped to your feet actually allow good footing on a oily/greasy floor? Not really.
Bad Boss / You Have Outlived Your Usefulness: The 4 bank robbers at the beginning of the film are quietly reminded by the Transporter that the conditions to using his car as a getaway car is that there is to be 3 bank robbers due to their weight, which with an added body would counter the shock absorbers he has installed. So, one of the bank robbers shoots another in the head and tosses him out the door. And for added effect reiterates the deal in a desperate manner. They get caught anyway, but only some time after Frank has successfully evaded the police and delivered them to their drop-off point.
In 3 Johnson subverts the Affably Evil trope by shooting dead a mook who earlier had failed to 'recruit' Frank by force, and who interrupts his politely 'persuading' Frank to work for him.
Bait and Switch: In the opening of Transporter 2 Frank carves through a gang of carjackers to get to a prior engagement. It looks like another bank job as in the beginning of the first movie only for the doors to open and a horde of schoolkids to run out. In the next movie the 'package' turns out to be the girl who's in the car with Frank, not the bags the villains put in the trunk.
Brick Joke: The bank robbers in the first movie offer Frank more money to take them the rest of the way. Frank refuses because it breaks Rule #1. Later he's watching a news report which shows the robbers were caught after driving the wrong way down a one-way street.
Bullet Dodge: Frank does this even without Matrix-style superpowers! (in 2 when the Russian biowarfare scientist shoots at him in the corridor).
Driving Into A Truck: In the opening sequence, Martin drives off a bridge onto a moving car carrier, landing on a conveniently empty spot, then knocks off the car behind him and backs back off the truck.
Dull Surprise: Frank Martin has two basic moods: beating people up while scowling, and driving really fast while scowling. Sometimes, for variety, he does it with his shirt off.
Equal-Opportunity Evil: The various gangs and drug cartels seem very willing to hire people from all sorts of backgrounds.
Johnson, the Big Bad of 3, even suggests that Frank join his organisation after he thinks he's won. Nothing personal about being strapped to a bomb, ha-ha.
Every Car Is a Pinto: First film, a stationary car is T-boned by a car that's braking heavily and travelling slowly. Both violently explode into flames!
And again, when two of the Big Bad's cars run into each other in the finale, and explode for no real reason.
Explosive Leash: In the third movie Frank has a bracelet attached to his wrist that will explode if he gets more than 50 feet from the car. This causes problems when he's hunting down the Big Bad at the end; he has to bring the car with him. Even onto a moving train.
Fanservice: One in every film! Shu Qi in the first film (in a wet t-shirt and wet panties); Amber Valletta in the second (good lord, she practically asks Frank to look down her top in one scene!); Natalya Rudakova in the third (in a slinky gold lame dress for most of the film, not to mention the red hair and Youthful Freckles).
Guns Akimbo: As noted above, Lola, though memory seems to recall Frank doing this a couple of times. Just look at the poster (pictured above).
Hidden Badass: No one seems to expect a simple Transporter to be a Bad Ass former Special Forces operative. And remember the slimy gangster, Wall Street, who tried to have Frank's car blown up at the start of the first movie? The one who's always surrounded by henchmen, and comes off as a sleazy businessman and Dirty Coward? Turns out he's the only guy in the movie capable of giving Frank a half-decent fight. And something of a Blood Knight, what with telling Frank to "keep alive" so they can finish their earlier, aborted fight.
I Gave My Word: In 2 Frank has a Rule #4 which is "Never make a promise you can't keep." He promises to protect his young charge; when the boy is kidnapped the Big Bad informs Frank he's going to have to break that rule. Fat chance.
Jack: Frank, you promised you wouldn't let anybody hurt me! You promised!
Chillini: Never make promises you can't keep, my friend.
Improvised Weapon User: Light fixtures, fire hoses, bicycle pedals, sweaters, motor oil — the list goes on and on. One could call Frank the MacGyver of beating people up.
In 2 his weapons include coconuts, fire hoses, and an entire boat being renovated which Frank uses to crush a mook after knocking out the support props (the mook was stuck in the porthole).
Just a Stupid Accent: Frank is obviously British, being played by the Stath and all, but he was apparently in the U.S. Special Forces.
Kick the Dog: The Dragon in the first film spends most of his screen time kicking dogs in one form or another, starting with murdering one of his men on the off chance that they might talk. And then there's his speech to Frank and Lai in which he calls the latter a lying whore, accuses Frank of being dumb enough to let her trick him, and finishes with the following line about the 400 people they came to save from being smuggled in: "Just for the record there were 400 people in that container. Only three hundred ninety-five made it here alive."
The Ukrainian intelligence team in 3 shoot dead a police truck driver just to get their hands on the GPS system, even though they could have just threatened him. This is presumably so we don't feel bothered when Frank sends them over the cliff later on.
Kingpin In His Gym: The main villain in the second movie is practicing Kendo against multiple opponents in his introductory scene.
Kiss of Life: Frank steals one from a mook in the second movie.
A Match Made In Stockholm: Frank and Lai in the first film. He delivers her to the bad guys in a bag (letting her out at one point, causing her to nearly escape), and goes back to dole out some revenge when they try to blow him up with his car for breaking the agreement. Frank takes Lai with him (while she's bound) after she snuck into his getaway car. She repays him with sexual favors for this, and also to get him to dismantle her father's human transportation operation. Since he's also responsible for rescuing her, it kinda blends with Rescue Romance.
Lola: A Stripperifficblonde with smeared mascara, who totes a couple of SMGs, looks perpetually high on drugs, and wears hooker boots and a trenchcoat. Yeah, she can't be good news.
Chillini: A situational example-he's an Italian man in a white suit in a movie where the villains are drug dealers. Yep, he's a villain.
Offscreen Teleportation: Happens often in the first movie, particularly with Wall Street, his gangs of henchmen and Lai's dad, who all seem to be able to outrun speeding vehicles.
One-Man Army: If Frank was in the Special Forces before this comparatively easy job, it sends shivers down one's Goddamn spine of just what the hell he had to fight in the actual battlefields of The Transporter universe. Or the very concept that entire squads of warriors who are of Frank Martin's caliber exist in The Transporter universe....
Papa Wolf: Transporter 2 is one of the few times you'll ever get to see Jason Statham showing a soft (well, as soft as an unsentimental hardass like Statham can be) and sensitive side; specifically, his kindness towards children.
Switch to English: The Chinese father tells his daughter to converse in English with him (even though she speaks perfect Chinese), because language school was expensive.
Tempting Fate: In the second movie, after Frank, Jack, and Lola have avoided pursuit from cops by jumping their car from the top of a parking garage to another under construction. The car skids to a stop near the edge, Lola's side facing out.
Lola: (looking back) I think we lost 'em.
Frank: (looking past her as a helicopter rises into view) Think again.
Played straight when Frank is chasing the Russian (who's hanging onto a bus) by driving up the canal in a jetski. The Russian mocks "The Driver" by shouting that he's no good on water — cue an Oh Crap moment as Frank launches the jetski out of the water onto the road behind the bus.
Underestimating Badassery: A lot of the villains do this to Frank, with predictably (and awesomely) unfortunate results. If you didn't do this to Wall Street, the sleazy gangster from the first film, good on you.
Waif-Fu: The stick-thin Lola tries this on Frank. It's promptly subverted; she gets knocked off her feet. Then she changes tactics.
What Happened to the Mouse?: An Elite Mook from the first movie had a distinctive tattoo around his eye, carried a whip and took down Frank in one move. Frank wakes up much later, but what happened to the cool mook?
A better example is the second truck. Watch the convoy at the end closely: There are two semi trucks full of prisoners, but only one gets "rescued". Where did the other one go?
What the Hell, Hero?: In 2 when chased by police Frank tells Lola to let him drive so no-one will get hurt. Except all those cops whose vehicles Car Fu or land upside down.
Wall Street does this in the first movie. He has Frank beaten, has back-up right around the corner, and then leaves to let his mooks finish the job. Didn't the trail of bodies this person left convince you to maybe just finish the job yourself? After all, you were the only one who even gave him a challenge!
