William David Friedkin was an American film, television and opera director, producer, and screenwriter who was closely identified with the "New Hollywood" movement of the 1970s. Beginning his career in documentaries in the early 1960s, he is best known for his crime thriller film The French Connection (1971), which won five Academy Awards, including Best Picture and Best Director, and the horror film The Exorcist (1973), which earned him another Academy Award nomination for Best Director.

Cruising is a 1980 crime thriller film written and directed by William Friedkin, and starring Al Pacino, Paul Sorvino and Karen Allen. It is loosely based on the novel of the same name by The New York Times reporter Gerald Walker about a serial killer targeting gay men, particularly those men associated with the leather scene in the late 1970s. The title is a double entendre, because "cruising" can describe both police officers on patrol and men who are cruising for sex.
