The document compares and contrasts movie trailers and teasers. It discusses their differences in sound/music, voiceovers, use of special effects, mise-en-scene, and choice of titles. Trailers tend to have more music tracks, voiceovers introducing ratings and plot, reveal more dramatic scenes and special effects, and use titles related to the storyline. Teasers generally use a single track of music, limit voiceovers and revealing of plot details, restrict big special effect scenes, rely on mise-en-scene to convey genre, and use vague date titles without giving away too much of the storyline. Both aim to introduce the genre but trailers provide more information while teasers aim to tease without revealing
