The document discusses conventions of film trailers and how the student challenged some conventions in their trailer for a psychological thriller film. The student analyzed existing thriller trailers to understand typical trailer elements like increasing pace and dark lighting/colors. Their trailer starts slow and gets faster, shows the two main characters, and hints at a mysterious threat without revealing details. While sticking to some genre expectations like scary shots, the student's trailer does not provide a narrative, typical sounds, or reveal characters/plot fully like most trailers do.
