In January 1977, Voyne was the dentist to Skye Aubrey, the wife of executive producer Ilya Salkind at that time. Aubrey suggested him to Salkind because she thought he looked like Superman. Taking her advice, he was called for a screen test at Shepperton Studios for the lead role. Despite making a great first impression, he was dropped out in the end because he looked too old and didn't convey the youth, power and courage of the Superman.
