Titles and credits in film trailers serve important purposes. Titles give audiences information about the storyline or characters and are usually shown at the beginning or end of trailers. Credits at the end of trailers acknowledge those involved in making the film, like producers, actors, and directors. Placement of titles and credits depends on genre and editing pace, but production companies are often featured at the beginning while the film title is usually at the end to be remembered. Titles and credits fit genres through style elements - thriller titles are plain with mystery, while horror uses colors like red and bold titles to create fear.
