4Film Music* — As you know from Looking at Movies, film music (like film sound generally) can be diegetic or nondiegetic. Diegetic music comes from the story world: a character turns on a radio, for example, or performs, as when the classic rock and roller Buddy Holly (Gary Busey) plays his songs during concerts in Steve Rash's The Buddy Holly Story (1978).

4Foley Sounds and Other Sound Effects* — People often confuse Foley sounds with sound effects, but the two are separate categories of sound. Foley sounds correspond to characters' movements and activities (walking, dancing, trying on clothes), while sound effects relate to everything else that makes noise in a movie—animals, cars, machines, and so forth.

4African American Filmmakers — While contemporary filmgoers may know the work of successful African American directors such as Spike Lee, John Singleton, and the Hughes brothers, they might be hard pressed to name a single movie made by an African American before, say, the late 1960s.

4Voice Acting* — To get a sense of voice acting's importance, consider Oscar-winner Mercedes McCambridge's performance as Pazuzu in William Friedkin's The Exorcist (1973). If you have seen the movie and can't remember what Pazuzu looks like, that's because McCambridge's "character" is the demon who possesses twelve-year-old Regan MacNeil (Linda Blair).
