Though Bud Abbott's character in this film was named Peter Patterson and Lou Costello's character's name was Freddie Franklin, they addressed each other by their own, real names ("Heeeeey Abbott!") throughout the entire picture. The credits are the only place where their characters' names are used.
On 25 November 1954, the day after filming completed, Bud Abbott and Lou Costello arrived in New York City to ride on the first float of the annual Macy's Thanksgiving Day Parade.
Stuntman Eddie Parker, who plays Klaris the mummy, previously doubled Lon Chaney Jr. as Kharis in Universal's earlier Mummy films.
Lou Costello had been suffering from rheumatic fever prior to filming, hence his slightly wan appearance.
Lou Costello's daughter Carole Costello has a small part as a flower girl. She was 16 years old at the time.
