Olivia Newton-John was told to strip to her underwear for a scene in the film, but she found the notion so humiliating that she burst into tears and refused to undress.
Producers Don Kirshner and Harry Saltzman butted heads, so Kirshner resigned before the film was completed and later remarked that if he had his way, the film would never be seen again during his lifetime. The movie made it's home video debut on DVD in the UK two months after Kirshner's death.
The intention of the filmmakers was to launch the original pop band Toomorrow, as producer Don Kirshner had previously done with the TV series The Monkees (1965).
The experience of making the movie had Olivia Newton-John so disenchanted with filmmaking that it took a lot of coaxing to get her to agree to star in Grease (1978).
Writer-director Val Guest was never paid, so he filed an injunction against the production company, which resulted in the film receiving a very brief theatrical run. Guest won the lawsuit but never received a dime.
