Wayne's chain-wielding employee (Jason Ronard) is shown reading a comic book while Kenny is locked up in the storeroom. The comic is actually the first issue of Marvel's STAR WARS adaptation.
Both of this film's leads, Annie Potts and Mark Hamill, were in car accidents prior to principal photography. Potts got pins in her legs whilst Hamill got a broken nose.
Mark Hamill said of this movie around the time of production: "I insisted on looking different. And I'm only interested in the car, not even any girl, until Annie Potts came along. . . It's not a car movie. It's really a love story. And I'm so thrilled to be working with Annie Potts. She reminds me of Judy Holliday. She's a unique creature." Hamill years after the film first came out then said: "Corvette Summer (1978) is a great little picture and it's got sort of a title that's a misnomer because you sort of put it in one category when you first see it and you go, 'Oh gee, it's quite a nicely written, uh romantic movie.' And I enjoyed it immensely."
One of the customized Corvette Stingrays used in the film was discovered missing from the MGM Studio lot on 12 September 1977. The stolen vehicle was recovered by police later that same day.
