I was not much a of JD fan until I saw him as ED WOOD, then in SLEEPY HOLLOW and most recently in FROM HELL.  If you remember Bette Davis and Joan Crawford (and Bette's assessment of their respective careers):  Joan was the "movie star."  Bette was the "actress."  
Well, in my book, Johnny Depp is first and foremost an "actor," and after that, a "movie star."  He'll be around long after all those pretty faces such as Ben Affleck and Matt Damon have gone to the "has-been hell" of Z-movies. LOL.
