The adult movie theater scene in the film is the Paris Theatre, located at 8163 Santa Monica Blvd. in West Hollywood. The theater opened as the Carmel Theatre, a legitimate movie house, in 1926, and operated as a grindhouse and adults-only Paris Theatre from the mid-1960s until 1976, when the building was destroyed by a fire.
Vince Edwards and Chuck Connors had co-starred once before, 15 years earlier, in The Hired Gun (1957).
