Director Randall Hood died of cancer during post production in 1976. It was long rumored that Clint Eastwood came in to help finish the film as a favor to lead actor Jack Ging.
Hugo Friedhoffer was so upset by the death of director Randall Hood, which happened before the score was recorded, that he never scored another film. This is his last credit.
Shot in 1972. Director-producer Randall Hood then ran into production problems and the completed (but unedited) film languished on the shelf until Hood's death of cancer in 1976. It was the movie's star, Jack Ging, who took over, overseeing post-production to finally bring it to the light six years later, in 1978.
