Deadpan Snarker: The interview with Ewa in prison is a good example:
Kiler: Kiev, 1989. Beautiful Ukrainian autumn. Four natural born killers armed to the teeth and me, alone, with my trusty Kalashnikov. Ewa: Well, did you make it? Kiler: Killed in action. Poor me.
Delivery Guy Infiltration: To get to senator Lipski's office, Jerzy impersonates the Killer pretending to be a policeman pretending to be a pizza delivery guy. From a company named "KILER PIZZA", no less. He does bring actual pizza, though.
Guile Hero: Jerzy Kiler is the Trope Codifier, as far as the Polish pop culture 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.
Hitman with a Heart: Kiler invokes this to avoid taking contracts he doesn't like (read: any).
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.
Playing Both Sides: Pretends to work for both Siara and Lipski, two men who each want 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 in the criminal underworld.
Working-Class Hero: Before the whole Killer mess up, Jerzy was just a taxi driver living in a dingy apartment.
Ewa Szańska
Portrayed by Małgorzata Kożuchowska
All Girls Want Bad Boys: Subverted; Jerzy is not a criminal, but Ewa doesn't know that when she falls for him.
Clingy Jealous Girl: She's not happy that Jurek is meeting with Gabrysia. Her reasoning is that he's just wasting time, but that's clearly not the entire motive.
Show Some Leg: To the prison director, Mieczysław Klonisz, so she can get in 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 been pursuing 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 he eventually makes amends when the real Killer is captured.
Hair-Trigger Temper: He's pretty amiable, but when the Killer case comes out, so does his anger.
Inspector Javert: He's the one that arrested Jurek after he got framed and pursued him after Siara's men abducted him.
Red Boxing Gloves: Dons a pair during Jerzy's interrogation to give him a few cathartic punches.
Stefan "Siara" Siarzewski
Portrayed by Janusz Rewiński
Affably Evil: For a big and dangerous mafia boss, he's pretty chummy in person, especially to Kiler.
Beard of Evil: He's a gangster played by Rewiński, an actor known for being bearded. You do the math.
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).
Embarrassing First Name: Probably the most famous example in Polish pop culture. She goes by "Gabrysia", because her actual first name "Ryszarda" is a Tomboyish Name.
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 gives her 300 dollars and she proclaims she could only buy swabs with that. That line went a bit memetic, actually.
Ferdynand Lipski
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's able to get any solid evidence that Lipski is corrupted.
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.
Golf Clubbing: Angrily smacks Siara's "corpse" with a golf club before Jurek stops him under the pretext that "Desecrating the Dead was not in the contract".
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!
The Killer
Portrayed by Sławomir Orzechowski
The Dog Was the Mastermind: The drunk client in Jerzy's 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 doubt that he even exists.
to help him craft a "hitman" persona.
Fountain of Memes: The movie as a whole is a source of endless quotes in the Polish popculture, but Siara easily takes the cake.
