[[caption-width-right:350:''"I can't really remember when I last had any hope, and I certainly can't remember when anyone else did either."'']]
->'''Played By:''' Clive Owen

A former activist who was devastated when his child died during a flu pandemic.
* ActionSurvivor: He's had no combat experience, and his only real credentials are that he was a protester with Julian. Still, he manages to make it due to determination and guile.
* TheAlcoholic: A subtle example.
** FunctionalAlcoholic: His mild alcoholism doesn't really impede him in any way. He drinks the dull his pain, not to get drunk.
* BadassLongcoat: In keeping with the realism of the film, Theo's coat is pretty shabby and worn. It's still cool, though.
* CigaretteOfAnxiety: [[spoiler:After Julian's death; his hands are shaking and he can't even light it.]]
* TheCynic: He's extremely embittered by the world and his own hardships, as exemplified by his conversation with Jasper.
-->'''Jasper:''' So, the Human Project is havin' this dinner and all the wisest men in the world are there...
-->'''Theo:''' Human Project, why do people believe this crap? You know even if these people existed with these facilities in these secret locations, fuck me, that's strong! Even if they discovered the cure for infertility, doesn't matter! Too late. World went to shit. Know what? It was too late before the infertility thing happened, for fuck's sake.
-->'''Jasper:''' ...I was just tryin' to tell a joke, man.
* DeadpanSnarker
* DespairEventHorizon: Went through it years prior to the film after the death of his son.
* DoesNotLikeGuns: A bit more subtle than most, but throughout the film, Theo never once picks up a firearm. Hell, when he kills [[spoiler:Syd]], he uses a blunt object.
* EmptyShell: How he seems to get through the days at the start of the film.
* TheHeroDies: [[spoiler:Theo takes a bullet from Luke and ends up expiring on a rowboat after getting Kee to the Human Project.]]
* HeroesWantRedheads: He certainly wanted Julian.
* HeroicSacrifice: [[spoiler:He make sure that Kee gets to the Human Project, even if he dies in the process.]]
* KnightInSourArmour: Theo is a bitter, alcoholic cynic but he has a good heart and will do the right thing.
* PermaStubble: He sports a constant unshaven look.
* UnlikelyHero: An alcoholic, cynical office worker with a rather dark view of humanity.
* WorkingWithTheEx: When he agrees to help Julian.

!!Julian Taylor

The leader of the Fishes and Theo's estranged wife.
* DeadpanSnarker
* DeadStarWalking: [[spoiler:Probably the biggest name in the film aside from Michael Caine, but she dies early on to help set the plot in motion.]]
* FieryRedhead: Averted. She's rather cool and careful, although she's still a RebelLeader with big plans.
* RebelLeader: Of the 'Fishes', a terrorist/rebel group fighting for the right of immigrants.
* WeHardlyKnewYe: [[spoiler:She dies before the film hits the halfway mark, shot in the neck by Patric.]]
* WorkingWithTheEx: She needs Theo's cousin's connections to transport Kee.

->'''Played By:''' Pam Ferris

* GranolaGirl
* HeroicSacrifice
* TheLoad

->'''Played By:''' Creator/PeterMullan

* AssholeVictim
* {{Badass}}: He did manage to make it into Bexhill in disguise and considering his job, he's no slouch. [[spoiler:Theo barely escapes him.]]
* CharacterDeath: [[spoiler:Theo smashes his face with a car battery.]]
* DeadpanSnarker: Probably one of the funnier characters. In a film like this, it's dark humor indeed.
* EvenBadMenLoveTheirMamas: Syd makes a passing mention that he loves his mum, though it doesn't come off as sincere as he thinks it might be.
* FauxAffablyEvil: He makes jokes and plays a horrible prank on Theo early on. His idea of what's funny is clearly only funny to him (and the audience). Hes very fun to watch.
* JerkWithAHeartOfJerk: Syd is a helpful enough guy at first and seems like he might be a good man at heart, but the reality is that he's a craven opportunist.
* OnlyInItForTheMoney: Why he [[spoiler:betrays Theo.]]
* ThirdPersonPerson: Refers to himself in such a way.
* {{Troll}}: As evidenced in his first encounter with Theo; he plays a terrifyingly sadistic prank on him.
* ViolentGlaswegian

* {{Jerkass}}: Patric is an aggressive, violent jackass with virtually no intelligence and the impulse control of a toddler.
* MoralMyopia: [[spoiler:Patric wants to kill Theo because Theo killed his cousin...who was trying to kill Theo at the time.]]
* NumberTwoForBrains: He's impulsive and stupid, never thinking things through.
* PsychoForHire: It's hard to imagine Patric was hired for anything other than his ability to shoot guns indiscriminately.
* YouHaveFailedMe: [[spoiler:Luke threatens him with this after he massively screws up by coming back to the Fishes' hideout, thus alerting Theo and allowing him to escape with Kee.]]

->'''Played By:''' Danny Huston

Theo's cousin and a high ranking government official.
