Keaton and O'Connor
I am a little disappointed that no one has really tackled a Peter Lorre bio. Drug addiction, illness, fame, defiance, affairs, the red scare, poverty, and one of the most waster talents Hollywood's ever seen? Really? No love? I have no idea who could even play Lorre. Maybe Pete Doherty if he could act - he's got the look, accent and addiction part down. After seeing Hopkins dressed up as Hitchcock he might make a good Sidney Greenstreet, Clooney or.. oh man this hurts to say... Ben Affleck (based on looks alone) as Bogie, and maybe Ewen Bremner from Trainspotting as Bertolt Brecht (seriously, look those two up. Dead ringer)... but I digress.
