Robert North Bradbury often seemed to add a pinch of the offbeat into his westerns, but when it came to directing his son, star Bob Steele, there was a downright oedipal underpinning because, quite often, Bob was thrust into an onscreen situation in which he lost his father.
Big Calibre utilizes this plot situation yet again, but regardless what Sigmund would have to say about it, it is of little consequence to this enjoyably odd oater. Bob’s father is killed and robbed of his cattle cash by a local chemist, played by screenwriter and Steele friend Perry Murdock. Bob pursues him, but the chemist escapes. Some time later, Bob, still in pursuit of his father’s murderer, is accused of holding up a stagecoach and murdering Peggy Campbell’s father, who also was robbed and killed with corrosive gas while en route to save his ranch from foreclosure.
