This document analyzes and summarizes three film trailers from different genres: horror, sci-fi/horror, and comedy. For the horror trailer "The Woman in Black," it notes the use of dark imagery, scary music, and supernatural elements that are typical of the genre. The sci-fi/horror trailer for "Alien" combines elements of both genres by setting it in space but also creating isolation and tension. Finally, the comedy trailer for "Ted" uses upbeat music, comical scenes and conversations, and light atmosphere rather than the darkness of horror trailers.
