Oh, I think he was unhappy with bourgeois life in St. Louis. I assume he was effeminate, that he was teased as a kid, and that was an unpleasant reality. In his introduction to Sweet Bird, Tennessee wrote that he was called a sissy by neighborhood kids, because he preferred reading and other solitary pursuits. He was an incredibly sensitive artist. I have no idea.
Any great writer writes imaginatively.
The autobiography in Sweet Bird is probably much less important than what Tennessee is saying about human existence, survival instincts, Puritanism, and this American mania for youth and for success which I think is stronger now than when Sweet Bird was written. That's the reason I want to do the play now. First, I think Elizabeth Ashley is a resourceful and hard-working actor. She is a Southerner and therefore truly knows the world of Tennessee Williams. She has an extravagance that is probably ideal for the role, and she has led such an interesting life.
