A drama film uses clever writing and editing to make audiences relate to and sympathize with characters. It keeps viewers interested through climaxes and lulls in tension. Conventions include peaks and troughs in the storyline, relatable characters, character relationships, and realistic plots. Trailers contain cliffhangers, release dates, climactic music, and character introductions. Posters focus on main characters and link to the plot, setting, and title in big letters. Effective posters attract audiences without revealing too much of the story.
