Filmed in Spain on a miniscule budget while William Shatner was on hiatus from playing Captain Kirk on Star Trek (1966), this film features him playing the dual role of half-breed twin brothers in the Old West.
This film is listed among The 100 Most Enjoyably Bad Movies Ever Made in Golden Raspberry Award founder John Wilson's book THE OFFICIAL RAZZIE® MOVIE GUIDE.
Normally hairy-chested William Shatner was forced to subject himself to a complete body waxing before appearing buffed and shirtless before the camera.
