Only twelve cast members are listed in the opening credits. Cathy O'Donnell receives an "and introducing" credit before her name. Victor Cutler, who plays Woody, is listed last in the opening credits but does not appear in the cast list of 23 names in the end credits.
The character played by Ray Teal (the Axis sympathizer whom Homer Parrish attacks at the soda fountain) is listed in the credits as "Mr. Mollett". However, the character's name is never mentioned or otherwise alluded to.
