The document discusses challenges to conventions in movie posters and trailers. For a teaser trailer, a shot is included of a mysterious character subtly shown in the background of a romantic scene, leaving their identity ambiguous. The poster features a modified quote from a famous actor about "the camera never dies" to reference death and intrigue viewers. Both the trailer and poster aim to disorient audiences and leave them wanting to rewatch or learn more without explicitly revealing details upfront. This challenges conventions by subtly incorporating mystery and ambiguity.
