Although she plays his mother, Kay Medford was less than 3 years older than Sid Caesar.
The scene where Bobbi (Arlene Golonka) models the sexy stripper outfit in front of George (Sid Caesar) isn't in the book. It was added to include some sex appeal to the film. Reportedly, William Castle approached Golonka and asked her if she'd be willing to film it topless, though her breasts wouldn't be visible onscreen, but she wasn't comfortable with that.
Final film of Marina Koshetz.
Based on Donald E. Westlake's novel of the same name.
