In this slapstick comedy thriller, Abbott and Costello play would-be radio writers who find themselves involved in a real murder during the recording of a “whodunit” play. Trying to solve the crime, they are targeted by the killer and suspected by the police.

A madcap chase through the radio station features a riotous encounter with a fitful drinking fountain, a mix-up in a sound recordings library, and a runaway elevator. With a strong supporting cast including Mary Wickes as a wisecracking secretary and William Bendix as a cop who’s even dumber than Lou. Who Done It? Has been called “one of Abbott and Costello’s best.” by critic Leonard Maltin.
