Recycled Wardrobe: The antique police (Keystone Cop) uniforms worn by the Angels can also be seen in The Legend of Lizzie Borden (1975) starring Elizabeth Montgomery.
The gangster costumes worn by the two men following the Angels at the car show are patterned after the outfits worn by Kirk (William Shatner) and Spock (Leonard Nimoy) in the classic Star Trek episode "A Piece of the Action".
Repeat costumes: Kelly later wears the same white anorak jacket in Angels in Waiting (1979). In that episode, she wore it in one scene, on the beach.
Lee Travis who wrote the story and Edward J. Lakso the Story Editor would later marry.
