The 1955 Thunderbird that Lori Nelson drives was actually her own car. The script called for her to drive a sports car but there wasn't enough money in the budget to rent one, so she offered to drive her own car, which the company gratefully accepted.
In 1956 American-International Pictures released this film on a double bill with Girls in Prison (1956).
Frank Gorshin would re-team with director Leslie H. Martinson ten years later for the movie version of Batman: The Movie (1966) in which he played "The Riddler".
Del Erickson who plays little brother Steve was born in 1943, so he was 13 in this movie, yet he was driving.
