Andy Kauffman had the alternate identity of Tony Cliffton, and he kept the fact that they were the same a secret (though many eventually found out, and then he had others play the part). What did Andy do about residuals when playing Tony Cliffton (for whenever Tony acted on-screen)? Wouldn't the producers or whoever was in charge of residuals need to know how to contact him?
Did Andy Kauffman eventually admit that he was Tony Cliffton? It seems like it's a known fact that it was Kauffman as Cliffton in The Fantastic Miss Piggy Show (as opposed to his writer or brother), did The Jim Henson Company know it at the time?
And did Andy Kauffman's manager really not know that Tony Cliffton was Andy until after he made a demand for Cliffton to have guest appearances on Taxi, like it is dramatized in Man on the Moon? In fact there's a few more things I'm wondering that I think I'll ask in the "what's the deal?" thread (because biography movies often change things for storytelling and dramatic purposes).
