Typefaces are sets of fonts that share design features, and can be categorized as serif or sans serif. Typography has a history dating back thousands of years. Typefaces play an important role in films by helping set the genre through factors like movement, color, and positioning. For example, the black and white capital font used in the opening of the film "Face/Off" suits the creepy thriller setting and creates an eerie atmosphere. Choosing different fonts, sizes, and colors can significantly impact audience perception of a film's genre.
