This film originated the "shooting the swordsman" gag that was popularized in Raiders of the Lost Ark (1981). A similar scene was recycled into the plot of the film Fit to Kill (1993) where a hitwoman with a machete was shot.
There is no credited composer on the film. Writer/Director Andy Sidaris may have possibly used music from ABC's Wide World of Sports vast music library to score the film since Sidaris worked on that show for more than a decade. Even the music tracks aren't credited to specific composers during the end credits.
One of the last films released by American International Pictures as the company would become Filmways Pictures a year later with Brian DePalma's Dressed To Kill being one of their first releases.
This film did not receive a DVD or Blu-Ray release until this year, 2018 which is almost 40 years after the film was produced and released, which was 1979.
Prior to Directing this film, Andy Sidaris was a Director for ABC Sports starting in the late 60's winning 7 Emmy's for his work during the Olympics in 1968 and 1976. He used the experiences directing on that show for this film because of the style and look of it.
