Jack Reacher is an adaptation of Lee Child's 2005 novelOne Shot.A man with a sniper rifle goes to a parking garage overlooking the Allegheny River in Pittsburgh, and kills five people across the river in the park, seemingly at random. The police are quick to find evidence and the man, James Barr. When they have him in for questioning, he writes "GET JACK REACHER" on a notepad. Before they can contact Reacher, the man is brutally beaten by fellow inmates.Reacher arrives and begins to examine the case, discovering the murders are not as cut-and-dry as they seem...
Tropes in Jack Reacher:
All Girls Want Bad Boys: When Jack asks Sandy why an intelligent, attractive, and nice teenage girl like her would put up with losers like Jeb Oliver and his crew, she says: "It's what girls like me do." She even hits on Jack again, because she believes he's a bad boy or at least a strong man.
Reacher: I can't afford you. Sandy: I'm not a hooker. Reacher: Oh, then I really can't afford you. Sandy: Seriously, I work at the auto parts store. Reacher: What I mean is, the cheapest woman tends to be the one you pay for. Sandy: I am NOT a hooker! Reacher:(giving up) Well, a hooker would get the joke.
Enemy Mine: Barr is invoking a form of this when he asks Emerson and Rodin to find Jack Reacher. Reacher despises Barr for his crime in Baghdad that he got away with and even promised to bring him down if he ever slipped up again. But Barr also knows Reacher's the only man who can see through the evidence and determine that Barr wasn't the shooter and figure out who framed him.
Fair Play Whodunnit: A surprising place for it, but adhered to religiously. All the information Jack needs to solve the crime is provided in the first five minutes of the movie, the viewer just has to realize that everything is important;
The setup: Five people(one sitting on a park bench, four walking around) murdered by a sniper from across a river, the location verified by shell casings on the scene. A quarter recovered from a nearby parking meter has the murderer's thumbprint on it, and a sixth bullet recovered from the attack matches a precision rifle in his possession.
The payoff: It's an Orgy of Evidence, meant to cover for a set of Serial Killings, Specific Target. A sniper skilled enough to make five kills at that range would never choose to fire from across a river, with targets walking left and right, unless there was no other choice - a preferred sniping position is where targets have to walk towards or away from the shooter, such as a nearby bridge where one could fire from inside a vehicle, which would also prevent shell casings from being lost. The first target was sitting still, which would let the sniper determine windage and bullet drop, meaning the second target was the intended one. Also, a sniper skilled enough to make five kills at that range and that position wouldn't have missed with the sixth - unless it wasn't a miss, but a successful shot into a target which ensured that a pristine bullet would be recovered. Finally, the only sniper who would pay for parking would be one who wanted to leave evidence behind - and the only cop who would check the meter would be one who was part of the conspiracy.
Final Boss: Charlie, who is the only one to give Reacher a decent fight in the climax.
Fingore: Zec had to bite off some his fingers during his imprisonment in Siberia. He tests the fortitude of one his hired men by forcing him to try to do the same.
Foreshadowing: When the movie actually takes a break from the investigation of James Barr to show video of each person who ended up shot going about their business leading up to being shot in the park, you know one of them will actually be important to the plot or they would simply be mentioned in an offhand manner.
Frameup: Sandy is murdered and Reacher is framed for it, as an attempt to tie up both loose ends.
Good Is Not Nice: Reacher can come across as a real asshole, often insulting and bullying people even if it's for a good cause.
Grievous Harm with a Body: Downplayed, but no less effective; in the bathroom fight scene, Reacher knocks down one guy onto another and smashes the top guy's head into the bottom guy's until both are out.
Homeless Hero: Reacher lives almost completely off the grid, the only means of tracking him being his withdrawals from a military pension account (which would require a federal warrant). He lives out of motels and gets his clothes from the Goodwill. He rationalizes this as a way to be free, pointing out that all the normal trappings of life serve to limit that freedom, and even claims that others would do the same if they could.
Hostage Situation: Defied by Reacher. Though he's going to rescue the girl, he refuses to do it by their rules, and warns that a man like him will be no end of trouble if so inclined. He instead forces them to give up their location, then attacks on his schedule.
Improbable Aiming Skills: Gunny in the final shootout, considering he's deliberately trying to avoid lethal shots. This makes some of his shots, like the wounding of one of the badguys straight through a wall or a quick, hasty shot that knocked the rifle out of Charlie's hand, all the more impressive.
Infant Immortality: In the opening sniper scene, Barr's final target is a woman running for safety, carrying her very young daughter with her. Despite showing the results of the other four shots, we only watch the sniper pull the trigger, then pack his rifle away. Later in the film, we see the scene play out again from their perspective, but the shot cuts before the bullet hits either of them.
It's All About Me: The Zec is motivated solely by his own survival. As a Russian refugee in his late 60s with three fingers left, crime was the only way he could find to pay his bills. He's willing to torture or kill anyone to make sure he isn't caught.
It's Personal: During the final showdown, Reacher catches the Zec's Dragon off-guard and has him at gunpoint. Rather than simply gun him down, Reacher has him disarm then fights him hand-to-hand, making good on his earlier Badass Boast in retaliation for Sandy's death.
Let's Fight Like Gentlemen: When Reacher confronts Charlie, he disarms him, then throws away his own gun so they can have a fistfight.
When Reacher tracks down Sandy after the bar fight:
The look on the Zec's face when the man who would do anything to survive realizes he's just talked himself into a death sentence.
In the epilogue, Barr's reaction to the crimes he's accused of (now that he can't remember not doing them) is equal parts regret for supposedly doing them and fear of what Reacher will do to him as a result.
Orgy of Evidence: Reacher quickly realizes that this is the case against James Barr. Too bad he missed the key element until the very end; only a sniper who wants to plant evidence would pay for for parking and thereby leave a thumbprint on the quarter, but only a crooked cop would know to look for said quarter.
Pittsburgh: A lot of footage of the Allegheny River across from PNC Park and the Fort Duquesne Bridge. (In fact, you can see the sniper's nest in the Pittsburgh page image, between the closest two bridges on the left. Gives you an idea of how far he was shooting, too.)
Precision F-Strike: Emerson and Rodin ask Helen where Reacher is. She says she doesn't know, and Rodin tells Emerson he thinks she's telling the truth. Helen spits back, "Oh, you 'think', Dad?! Fuck you!"
Pre-Mortem One-Liner: When the Zec taunts Reacher at the end to see which one of them will go to prison, Reacher replies, "My bet? Neither one." He then shoots the Zec in the head.
Red Herring: Reacher spots a possible connection between two of the victims, who he suspects were having an affair. This has nothing to do with why it happened, only serving as an example of how what seems like a coincidence may be something more.
Refuge in Audacity: The Zec is convinced that he'll avoid prison after all his mooks have been killed, reasoning that the former military homeless guy is a much more likely suspect than a nameless old man missing several fingers, so long as he can eliminate any other witnesses. Reacher agrees... then kills him in cold blood.
Serial Killings, Specific Target: The Entire Plot.The owner of a local construction company was the intended victim. The other four murders were just to disguise this.
Sherlock Scan: Reacher is pretty good at these, probably due to his wide range of experience as a former military policeman.
Shout-Out: Both of Reacher's aliases (Aaron Ward and Jimmie Reese) were baseball players for the New York Yankees.
Shrouded in Myth: Other than the official records they have on him from hist time in the military, nobody knows anything about Jack Reacher other than he exists, is out there somewhere, and is a total Bad Ass.
Sociopathic Soldier: Jack lists four different types of soldiers that he knew from experience — Military Brats who followed their parents into the military, patriots, people looking for work, and people who join so that they can kill without repercussions. James Barr was the last type, having eventually snapped and gone on a shooting rampage in Baghdad just so that he could feed his urge to kill; the only reason he got away with it was because, unbeknownst to him, his victimsall had it coming, and the PMC that they worked for didn't pursue justice because they knew that the victims' crimes would be exposed if they did so.
Charlie is implied (stated in the book) to be ex-military, and is a stone-cold killer.
Reacher fully believes that Barr is the shooter and is there only to make sure he goes down...until he sees the quarter with Barr's fingerprint on it with the evidence. Not only does it make no sense for Barr to make sure he's paid the parking meter right before shooting five random people in cold blood, but it also makes no sense for Emerson to investigate the meter unless he knew the quarter would be there beforehand.
Next, with a seed of doubt in his mind, Reacher investigates the location of the shooting and deems it a poor vantage point due to the location of the sun and targets moving left-and-right. He finds another location nearby that would have been ideal for a shooter and would have prevented empty shells from being left behind as evidence. He also discovers that Barr was deemed a merely 'decent' sniper while in the Army and wasn't good enough to shoot so accurately from a non-ideal location.
All six shots that the sniper fired came in quick succession...except for a several second pause between shot one and two. Reacher determines that this means the sniper was extra careful with his second shot, meaning the second target was killed for an actual purpose. Serial Killings, Specific Target.
Five of the shots the sniper took were perfect, while the fourth shot missed by a lot and ended up in a location where the bullet would be preserved perfectly to be used for evidence. Reacher reasons that the shooter intentionally put one of his rounds in a perfect location to be found by police for the evidence in the case against Barr.
Reacher uses a fake name when Sandy approaches him at a bar, and sees she's thrown by it even though she had no reason to be. From this, and the barfight that follows, he believes that someone is trying to run him off the case, which leads to him eventually blowing the entire plan.
Jeb hasn't been seen for awhile by his friends, who all think he's left town. Reacher checks his house and finds evidence that Jeb quickly packed some things and left...except the shower curtain is gone too, leading him to think that someone (who wasn't very smart) simply raided the house to make it look like Jeb had left—or perhaps the curtain made an ideal drop cloth for a body.
