Peter Lorre almost always played the sad eyed villain from forties until has death in 1964 at the age of 59 years old. We loved watching him in film noir playing sinister characters. The years before his death - we enjoyed his low budget horror flicks at the drive-in produced by Roger Corman. Lorre is so much fun to watch.
I will say this. There was never a doubt in my mind that the guy was a sweet fellow. Peter Lorre, like Moe Howard, is a man that I would have liked to have met and had a conversation with. This short Youtube clip reflects a little of the kind of guy Peter Lorre was like in real life. He played the creepiest bad men - but boy wouldn't it have been great to have had met him.
