Let us be honest... These are better than the recap itself.
Sam is Health Ledgers Joker (The Dark Knight)

I almost gave myself the Joker, but Sam is just insane beyond belief and will do anything to hurt you. Maybe he is just angry about being short. Who knows his motives, who knows what he is going to do next, but Sam perfectly resembles this freak.
Pags is Jack Torrance (The Shining)

I don't know why, but I can totally see Pags as a failed writer who then goes mad and decides it is necessary to murder his wife and child all after attempting to become a caretaker at a Hotel. I can also totally see Pags delivering the "Here's Johnny!" scene.
Graham is Jason Vorhees (Friday the 13th)

The only reason I did this one is because Graham is always talking about that summer camp where he met that chick Sierra Mist; and all I can think of is if it all went wrong, and Graham turned into the camps serial killer.
Britton is Norman Bates (Pyscho)

Well, I guess you could make the connection that I rarely leave my house during the weekends, and most of you assume it is because I am a loner, but maybe I prefer chilling by myself and maybe I am a killer who is haunted by his mothers ghost. Nah, If I was haunted by Peggys ghost I would just be dishing out ghostly brownies. But yes, I might be insane.
Mark is Ivan Drago (Rocky IV)

You get it...
