Frank's Cock is a 1993 Canadian short film written and directed by Mike Hoolboom. The eight-minute production stars Callum Keith Rennie as an unnamed narrator who discusses his relationship with his partner, Frank. The two met while the narrator was a teenager and spent nearly ten years together. Frank has since been diagnosed with AIDS, and the narrator fears his death. The story was based on the experience of one of Hoolboom's friends at People With AIDS, which Hoolboom adapted after receiving a commission to create a short film about breaking up.

Michael Hoolboom is a Canadian independent, experimental filmmaker. Having begun filmmaking at an early age, Hoolboom released his first major work, a "film that's not quite a film" entitled White Museum, in 1986. Although he continued to produce films, his rate of production improved drastically after he was diagnosed with HIV in 1988 or 1989; this gave a "new urgency" to his works. Since then he has made dozens of films, two of which have won Best Short Film at the Toronto International Film Festival. His films have also featured in more than 200 film festivals worldwide.
