When they arrive in Hollywood, Anita Ekberg is starring in a movie where she plays Napoleon's lover. That same year, Ekberg was featured in War and Peace (1956), another Paramount release, which included Napoleon as a character.
The original screenplay by Erna Lazarus concerned the adventures of a down-on-her-luck ex-chorus girl and a con man as they made their way to California. It was conceived as a vehicle for Shirley Booth and Humphrey Bogart. By the time Frank Tashlin got through re-tooling it for Dean Martin and Jerry Lewis, it bore little resemblance to the original script. Nevertheless, Lazarus retained the sole writing credit.
