Frederick Alvin Kelsey was an American actor, film director, and screenwriter.

Who Killed Who? is a 1943 Metro-Goldwyn-Mayer film noir animated short directed by Tex Avery. The cartoon is a parody of whodunit stories and employs many clichés of the genre for humor; for example, the score is performed not by the MGM orchestra but by a solo organ, imitating the style of many radio dramas of the era.
