Guile Hero: Jerzy Kiler is the Trope Codifier, as far as the Polish popculture is concerned. With careful planning, some Indy Ploys and the help of his friends, he manages to outwit both the police and the bad guys (including the real Killer), get the girl and acquire a container full of money.
In Love with the Mark: Subverted; he was already in love with Ewa when Siara ordered him to kill her. Of course, he never intended to do the job.
MacGuffin Delivery Service: The reason Siara ordered him to kill Lipski is to acquire his half of the 2000 Colombian peso bill needed to collect the cash from the cargo delivery. Jurek has different plans in relation to it.
Playing Both Sides: Pretends to work for both Siara and Lipski, each one wanting the other dead. He manages to convince each of them that he did the job, finally getting them out of the way.
Villain Cred: As he gets mistaken for the Killer, he becomes a respected and feared personality in society and the criminal environment.
Working-Class Hero: Before the whole Killer mess up, Jerzy was just a taxi driver living in a dingy apartment.
Show Some Leg: To the prison director, Mieczysław Klonisz, so she can get to interview Kiler.
Commissioner Jerzy Ryba
Portrayed by Jerzy Stuhr
Big Damn Heroes: He holds the real Killer at gunpoint when he's about to shoot Jerzy and his friends down.
Hardboiled Detective: A tough high-ranking oficer who's persistently pursued the Killer for three years.
Hero Antagonist: Puts Jerzy behind bars and is a major Jerkass to him during the interrogation, though it's all due to a misunderstanding and they eventually make amends when the real Killer is captured.
Fountain of Memes: The movie as a whole is a source of endless quotes in the Polish popculture, but Siara easily takes the cake.
The Starscream: Plans to get rid of Lipski to take all of the cash from the deal and intends that Kiler does the job.
Your Cheating Heart: According to Gabrysia he often drags girls to his apartment to have sex with them.
Ryszarda Gabrysia Siarzewska
Portrayed by Katarzyna Figura
Dumb Blonde: Downplayed; she's not outright stupid (has enough wits to figure out her husband's plan and tries to take advantage of Jerzy to take the cash for herself), but she is at least a little absent-minded (almost blows Kiler's cover at a restaurant, tells him to retrieve an important MacGuffin whilst having no idea who has it).
Gold Digger: Clearly only married to Siara for the money. At the opportunity of a huge gain, she is more than willing to usurp her husband and take the spoils.
Inheritance Murder: She orders Jerzy to kill Siara so they can split the money from the cargo delivery.
Rich Bitch: This is especially evident when Jerzy gifts her 300 dollars and she proclaims she could only buy swabs with that.
Your Cheating Heart: She's implied to frequently cheat on her husband, and clearly tried to seduce Kiler.
Portrayed by Jan Englert
Corrupt Politician: He's a senator and the "brains" to Siara's "brawn". It's common knowledge that they're in cahoots, but no one was able to get solid evidence of his corruption.
Et Tu, Brute?: Completely flips out when told that Siara wants his head off, as quoted below.
Evil Old Folks: His age is not specified, but he's the only notable character with a fully gray scalp, and certainly not a good guy.
Lipski: Siara? He ordered you to kill ME?! That half brain?! That cloned sheep?! That turd dressed up in a golden tracksuit?! He doesn't exist without me! Kiler: Would you like to talk about it, sir? Lipski:... With much fucking pleasure!
Portrayed by Sławomir Orzechowski
The Dog Was the Mastermind: The drunk that Jerzy was driving in his cab on the night of Guillotine's murder? That was the real Killer who framed Jerzy.
The Dreaded: He's (in)famous to the point that you would think he was John Wick. His rep alone allows Kiler to punch way above his weight.
Frame-Up: Successfully sells Jerzy out as himself by leaving his rifle in his cab's trunk and calling the cops on him while he's out to buy cigarettes.
Living Legend: He's as secretive as he's effective as a hitman, and he's VERY good at his job - to the point that some people doubted that he even existed.
