Character appearances: Grand Theft Auto 5
Actor seen in: Fright Night, Seven Psychopaths, and Horrible Bosses.
Possibly the zaniest main character in Grand Theft Auto franchise history, Trevor Philips is the instigator of several over-the-top sequences in the latest Rockstar Games title. As a result, Hollywood would need to find an actor that could "play crazy" convincingly - without resorting to parody or caricature. Fortunately, Colin Farrell has a filmography full of madcap but believable performances - and the Irish-born actor has managed to bring something new to each sociopath in his collection. Moviegoers will, no doubt, remember the actor's performances as Jerry (Fright Night) and Bullseye (Daredevil) but it is actually his 2011 turn as one of the Horrible Bosses, Bobby Pellitt, that got us thinking about how much fun it would be to see Farrell running around the world of GTA in the role of Trevor. Additionally, Farrell is no stranger to starring opposite other idiosyncratic personalities - meaning he'd likely heighten the performances of his Michael and Franklin co-stars as well as any demented antagonists the GTA 5 trio would undoubtedly face.
