@talk72000,
a) I surmised that from articles years ago, but don't know that personally
b) I'll just jump to that the whole family seem to be loons. Which is none of my business.
c) why does this interest you? I don't mean that meanly - I do read the odd link to current phenoms to keep up with what seems to make the world turn.
I'm a hollywood kid, somewhat, and have some sympathy for those who work into the business. That is probably balanced by a lot of irritation.
