They're called trailers, because originally they trailed the feature presentation. But before long, movie marketers learned there was a better chance of grabbing the audience's attention before the film. Trailers have since gone on to become one of the quintessential elements of movie-going, as illustrated in this documentary from Michael J. Shapiro and Jeff Werner. Featuring interviews with Joe Dante, Leonard Maltin, voice-over artist Don LaFontaine and several others, Coming Attractions: The History of the Movie Trailer traces a century of movie previews. ~ Matthew Tobey, Rovi
