The document summarizes three movie trailers: 1) The Lucy trailer uses quick cuts between scenes of the main character at a club and other locations to create intrigue without providing context. 2) The Avengers trailer starts with slow fades between scenes and a voiceover by the antagonist to set the crime/action genre. It shows the protagonists needing to team up to defend Earth. 3) Both trailers use techniques like explosions, camera angles and editing to build excitement and convey the action genres.
