The radio broadcaster at the film's ending announcing the death of Jayne Mansfield says, "Miss Mansfield was 36 years old". In fact, Jayne was 34 years old.
In a scene towards the film's ending, Jayne is seen filming a movie called Las Vegas Hillbillys (1966) with Mickey on the set. Jayne had been divorced from Mickey for almost two years when the movie was made. It also shows Las Vegas Hillbillys as a Western which it was not.
When Jim Byron is walking into the car dealership to see Jayne and her new make-over, a 1980 Honda Civic is seen passing by as he opens the door. This part of the film takes place in the 1950s.
