Surprised no one's mentioned it yet, but a trailer I first saw in a theater in November 1979 comes to mind:
Star Trek - The Motion Picture.
I think it can be seen on YouTube. Orson Welles names the cast and their roles, and gets to say "The human adventure is just beginning." There's no hint of the movie's rather disappointing, derivative plot. Yes, after more than 29 years of contemplation, I do think it was a terrible movie. (Although I do recognize Jerry Goldsmith's achievement turning out great scores for this and Alien in the same year; his Oscar-nominated TMP score should have won.)
