No, but I've heard nothing but good things.
Depp has been rumored to play Lex forever now, but no one has ever confirmed or denied his involvement. I doubt it, however, because his plate is very full with upcoming projects (Charlie and the Chocolate Factory, Pirates of the Caribbean 2, The Rum Diary, and The Diving Bell and the Butterfly).
He's 18, and Jimmy should look young.
As of this moment she's not even 20! I know they want a young cast, but she is a bit too young for the part.
He's supposedly been dropped from their list.
