No, trailers are done by different editors and directors, who are specialised on doing trailers. Still it sucks that most of them spoil the film rather than we the appetite. The last trailer I can remember which did not give away too much was fight club, which is one of my favourite movies, actually.
On topic: I too think that Craig is the best Bond since Connery, allthough I also liked Timothy Dalton. I dislike the Brosnan Bonds for their very effect and product placement driven movies, and not his performance.
