^ Recasting is bad enough, but jumping from one actor to another in the same movie? Awful idea.
The series will absolutely go on, but what of the current movie that's still filming? Some accounts say they've shot all of Walker's scenes and others say that they still have stuff to shoot. Will they have to write around his death? Will the bulk of the movie have to be redone? Are they in the clear? Guess we'll know more this week.
