Jerry Robinson on The Joker

“Bill Finger knew of Conrad Veidt because Bill had been to a lot of the foreign films. Veidt ... had this clown makeup with the frozen smile on his face (classic). When Bill saw the first drawing of the Joker, he said, 'That reminds me of Conrad Veidt in The Man Who Laughs. He said he would bring in some shots of that movie to show me. That's how that came about. I think in Bill's mind, he fleshed out the concept of the character.”

“They've given many origins of the Joker, how he came to be. That doesn't seem to matter—just how he is now. I never intended to give a reason for his appearance. We discussed that and Bill [Finger] and I never wanted to change it at that time. I thought—and he agreed—that it takes away some of the essential mystery.”
