Judy Arnold, women's Captain of the Philadelphia Warriors Roller Games team, doubled for Raquel Welch in the skating sequences. She also has a small speaking role in a dressing room scene. She had to wear a long wig for the skating scenes, covering her short blonde hair.
Phil Ochs, the folksinger-songwriter, was originally approached to write a theme song for this movie. His song was rejected, though. Ochs had A&M Records issue it as a single anyway.
Writer Barry Sandler got Raquel Welch interested in this project by showing up on her doorstep and leaving a script with her personal assistant. He was attending UCLA film school at the time.
Jodie Foster played Raquel's daughter in this movie. Foster was ten years old at the time of filming. This was Foster's second feature film, after Flucht in die Wildnis (1972).
The movie was shot almost entirely in Portland, Oregon. The bar scenes were shot in the World Famous Kenton Club, a popular "dive" bar that has gone almost unchanged since then.
