Arnold Schwarzenegger signed up for a glorified cameo as a favor to producer Dino De Laurentiis. Much to his surprise, he was on the set for four weeks, three weeks longer than expected. He discovered after watching a rough cut of the movie that his role had been expanded to co-star, thanks to crafty angles and multiple cameras. Soon after, Schwarzenegger decided to terminate his 10-year contract with De Laurentiis.
Arnold Schwarzenegger eschews this movie as one of his worst, yet he (laughingly) claims that it's an excellent disciplinary tool for his children. "I tell them, if they get on my bad side, they'll be forced to watch Kalidor : La Légende du talisman (1985) ten times in a row. It must be working, because none of my kids has ever given me much trouble."
Maria Shriver said in a TV interview that at the premiere, she remarked to her then-husband, Arnold Schwarzenegger, "If this doesn't kill your career, nothing will."
It took Dino De Laurentiis almost a year to find an actress "Amazonian" enough to play the title character. Eight weeks before production was set to begin, he saw Brigitte Nielsen on the cover of a fashion magazine. The 21-year-old native of Helsingør, Denmark, in Milan for a modeling job, soon found herself on a plane heading for Rome and a successful screen test.
