Johnny Depp's now said his confidence in the movie is shaken since a certain Fox executive that supported him for the first movie has left Fox (or something along those lines). I think the quote is that "There's a fissure, a crack in my enthusiasm at the moment" and it's since that guy was kicked out or quit. Bloom and Knightley aren't doing it either, but then again they're shit actors and were just eyecandy for various genders/sexual orientations.
