Hey Tom-
I'm going to go see the movie version tomorrow, directed by the Slumdog Millionaire guy (Danny Boyle) and starring James Franco. It's a private advance screening which I'm absurdly lucky to be attending and Boyle and Franco will be there for a Q&A. Though we've not seen the film of course, got any questions?
Ask him if he drank real piss from a jar to train for the role.
