->'''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.
* AgonyOfTheFeet: PlayedForDrama after Theo [[LosingAShoeInTheStruggle loses a sandal]], due to a scuffle with [[spoiler:Syd]]. He proceeds to cut his foot on some scrap metal, then either hop or limp his way through the rest of the journey.
* 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: He is extremely snarky.
* 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.
* FriendToAllLivingThings: As a Biblical allusion, animals love him and are attracted to him. Lampshaded when he visits the farm and dogs that are said to tear anyone else to pieces happily come up to him with wagging tails.
* FunctionalAlcoholic: His mild alcoholism doesn't really impede him in any way. He drinks to dull his pain, not to get drunk.
* 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.]]

The leader of the Fishes and Theo's estranged wife.

* DeadpanSnarker: Probably why she and Theo get along.
* 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.]]

* DarkAndTroubledPast: [[spoiler: Mentions near the end that he had a sister who died]].

* WellIntentionedExtremist: As with the rest of the Fishes.

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

* 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.
* EstablishingCharacterMoment: When Theo follows Jasper's orders and tells Syd he's a fascist pig, Syd pulls out a baton and pretends like he's going to beat Theo over the head with it as a [[{{Troll}} "joke"]]. Having just met him.
* 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.
* OddFriendship: Though they never appear onscreen together it's odd that Jasper knows and trusts him, considering Jasper's a NiceGuy and Syd is a JerkWithAHeartOfJerk.

* 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.

* CharacterDeath: [[spoiler:During the firefight in Bexhill, he gets shot straight in the heart.]]
* TheDragon: [[spoiler:To Luke.]]
* DroppedABridgeOnHim: It's set up like there's going to be a climactic fight between Theo and Patric, but [[spoiler:he is shot in the heart before that can happen]].
* EvenEvilHasLovedOnes: He did love his cousin, and is outraged when [[spoiler:Theo kills him.]] See MoralMyopia.
* HotBlooded: His default mode seems to be 'psychotically angry'.
* {{Jerkass}}: Patric is an aggressive, violent jackass with virtually no intelligence and the impulse control of a toddler.
* JerkWithAHeartOfJerk: It initially seems like Patric will be a JerkWithAHeartOfGold since he is on the side of the good guys...[[spoiler: until it's revealed that Luke is evil and Patric is his psychotic [[TheDragon dragon]]]].
* 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.
