Re: Depp. Not a big fan, but I liked him in Polanski's Ninth Gate.
Re: Barry Lyndon. I saw about 1/2 of it not too long ago channel surfing and thought it held up really well. Marisa Berenson was almost too pretty for the role but it is the only film that O'Neil could / should be proud of. My only complaint is really minor: the typography used for the titles. Very dated, very seventies and reminded me of a bad album design from the period.
