This document analyzes trailer conventions for a hybrid genre film starring Nicholas Hoult and John Malkovich. It notes that the full trailer introduces the title late at 2:18, credits the distribution company and stars, and uses changes in music and editing pace to suggest shifting between genres of horror, thriller, comedy, action, and romance. The teaser trailer also focuses on the stars, shows more action scenes to attract audiences, and uses intense non-diegetic music and diegetic sounds to transition between scenes and establish genres.
