Connery-Thunderball US Release Trailer
Lazenby-Rather obvious.

Moore-Live and Let Die trailer-the really long one, great use of the Bond Theme to get the audience drooling for more, and Moore for that matter.
TSWLM-Probably the best Bond trailer from the 70's, gives you the sense you're going to be seeing the most incredible adventure ever put on film.
Dalton-I like the first LTK trailer. Short, to the point and very cool.
Brosnan-I think that all the trailers up to TWINE are great. The TWINE teaser is good but the relkease trailer is mereley adequate, much like the film itself. I love all three DAD trailers.
