They don't really go to Mars, they go to Venus, but first they go to New Orleans. While working at a missile base, Bud Abbott and Lou Costello inadvertently launch a rocket ship with themselves aboard. After a wild ride around New York City (the Statue of Liberty ducks when the rocket heads her way), Bud and Lou land in the outskirts of New Orleans. The boys are convinced that they've reached Mars, and their faith in this supposition is affirmed when they come across several strangely costumed "creatures" (actually revellers at the Mardi Gras). Meanwhile, bank robbers Jack Kruschen and Horace McMahon stow away on A&C's rocketship. When Bud and Lou return, the crooks force them to make a quick getaway into outer space. After several days of weightlessness, the four space travellers land on Venus, a planet populated by the gorgeous winners of the Miss Universe contest (including Anita Ekberg). Venusian queen Mari Blanchard falls in love with Costello, only to order him and his companions to return to earth when Lou proves to be unfaithful. Reportedly, this bizarre melange of sci-fi and slapstick was based on a story by Charles Beaumont, who received no screen credit (it's worth noting that Beaumont's later Queen of Outer Space boasts a remarkably similar plotline). Long considered the team's worst film, Abbott and Costello Go to Mars ("and about time!" quipped the New York Times' TV-movie reviewer) is rather likeable in its own incoherent way.
