Holy crap, Colin Farrell is a *beep* actor
He is HORRIBLE in this movie, and is totally mis-cast. FAIL
shareTo OP. Yes, he plays himself in every single movie. When a character he plays is "very Colin Farrell like" then that's the first sign the characters he plays are interchangeable and way more associated with him than the characters they're written as.
When compared to the other actors in this film he feels like the odd one out.
