This document analyzes three film trailers: This Is 40 uses comical dialogue and up-tempo music with fast edits to represent its comedic genre, pausing for punchlines; Compliance uses fades and an eerie tone to intrigue viewers about a true story involving an unknown police officer and manager; End of Watch shows action from two perspectives very quickly without voiceover, using gunfire and its Fast and Furious writer to look exciting and help viewers connect with characters.
