The film was shot on location in Yugoslavia, and claims to be based on a true story. There are several versions, including an original three-hour cut made for Yugoslavian television, and a feature-length version for the American market. Rod Taylor was involved in rewriting and shooting some additional scenes during post production.[1]
The producer, Ika Panajotovic, was a lawyer and former tennis player who represented Yugoslavia in the Davis Cup and reached the semi-finals at Wimbledon.[2]
