Well it's true that the Gene Wilder one was less than faithful to the book but it is still a wonderful, memorable, brilliantly cast film and quite dark itself in a subtle sort of way. I'm not holding my breath for this one to be better.
I think the original film was darker than the book - and imagine that TB and JD will take that a step further. Not sure if I think it needs remaking but if anyone should be allowed to get their paws on to it it is those two.
I think its going to be amazing - the first film was too hapy clappy compared to the book (always got the feeling in the book that wonka was a bit of a sadistic lunatic - Dahl at his best )... if anyone is going to capture Dahl essence, then Burton and Depp have got to be the ones.
Dahl hated what they did with the first one (as much as we all loved it). Him and Burton both have the same warped minds, so it should be great,
I'm a huge Depp and Burton fan anyway though, so probably biased....
