I Killed Wild Bill Hickok presents a made-up account of how Johnny Rebel, also known as Johnny Carpenter, ended up shooting Wild Bill Hickok, portrayed by Tom Brown, who functions as the dishonest sheriff of Tri City following the Civil War. Honestly, it's not great; at just over an hour long, it feels like it could easily be trimmed by thirty minutes! Though released in 1956, the film has a vibe more akin to a Western from the 1930s. The production values, musical score, acting, directing (by Richard Talmadge), and everything else just feel misplaced within its time period. It’s often the innocent who suffer. The movie incorporates familiar elements of older Westerns—gunfights, troublesome Native Americans, chases, a romantic interest, and the standard good versus evil conflict—but these are strung together with stock footage and repeated scenes to artificially lengthen the film. There are several instances of horses simply running around that don't really add anything, though a particularly striking white Palomino is actually the most talented performer in the cast! The story culminates in a chaotic ending where Carpenter, who also produced, wrote, and stars in the film, battles practically the entire town single-handedly, receiving repeater rifles from Belle Longtree (Helen Westcott). This portion of the movie at least makes it somewhat worthwhile, showcasing some impressive stunt work. Talmadge doesn't demonstrate much directorial skill, but his background as a stunt man is clearly visible during the final fifteen minutes. View with care. 4/10
