Unfortunately, both Miss Potter and Elizabeth: The Golden Age didn't live up to the trailers for me. I was so EXCITED about Elizabeth, too, probably because I enjoyed the first one so much, that it probably could never live up to the version I had in mind. Still a good movie, but sometimes I like to watch the trailer and think of what might have been.

Sky Captain and the World of Tomorrow:

the robots, the retro 50s feel with an alternate reality storyline, this trailer got lots of people anxious, but sadly, none of them went to go see the movie. I did though, it was good, better then the critics gave it anyway.

V for Vendetta:

That trailer was phenomenal, it gave the basic plot, and promised twists, conspericies, and explosions. I loved the movie, and the trailer.

Cloverfield:

Probably the one trailer that got the most people to go see the movie. This is in my opinion, a perfect trailer. NYC is under attack from something, and that's all you know. I have yet to see a trailer that was as perfectly suited for a movie that succeded to well.

I saw all three of the movies i listed, but I only saw 5 of the ones you listed, and mostly not because of the trailers.

I am curious though, which movies didn't live up to the trailers in your mind?
