Lost in Harlem is the second of the pictures that Abbott And Costello did for MGM while they were working at Universal. It was common for studios to loan out stars to other studios. Often as punishment to keep the actors in line.
Lost In Harlem has a screenplay by Harry Ruskin, John Grant, Harry Crane and an uncredited Robert E Hopkins. The director was Charles Reisner.
The guys are stage magicians, not every good ones, who are touring the Middle East. They get involved with Prine Ramo and help him regain his throne. There's plenty of shenanigans as the guys run rampant through the palace. It made me laugh. It was packed on the two disc set with Abbott And Costello Go To Hollywood. A good addition to the comedy collection.
