Movie Info

Bob O'Neill (Bob Steele) is on the hunt for his father's killer. Because his father was killed using poison gas, O'Neill's prime suspect is a deformed, mysterious scientist named Otto Zenz (Bill Quinn). When Zenz skips town, O'Neill follows. Before he catches up with his target, O'Neill finds himself on the other side of the law after being accused of holding up a mail truck. But he won't give up, so he finds a way to continue his pursuit -- as a man on the run himself.

Audience Reviews for Big Calibre

  • Apr 14, 2010
    A chemist in the old West kills with vials of poison gas; when discovered, he relocates to another town and disguises himself as a bucktoothed hunchback until the hero tracks him down. A decidedly odd little B-western with vaudeville routines interspersed throughout; not for all tastes, obviously, but an interesting curiosity.
