Great supporting cast in this one: Joe E. Brown is hilarious, George Raft, Pat O' Brien. . . .
Trivia: Jerry Lewis was offered the part played by Jack Lemmon, but declined.
Trivia II: Cary Grant liked Tony Curtis's imitation of him as the millionaire. Grant and Curtis worked together on "Operation Petticoat" around the same time.
Trivia III: That "Florida" hotel was really the Hotel del Coronado in San Diego. When they're swimming in the ocean, you can see mountains in the background, which I don't think exist near Miami.
BTW, my mom remembered the actual St. Valentine's Day massacre. She was 13 years old at the time (Feb. 1929), and lived in Chicago not far from where it occurred.
I think Curtis said something about learning the Cary Grant accent while serving on board a submarine during WW2. They had only one film on board: A Cary Grant film.
Joe E. Brown and Lemmon dancing at the roadhouse....
Jerry with the marracas.
