To call The Beast Of Hollow Mountain (1956) a Western might be pushing things a bit. After all, dinosaurs don’t turn up in too many cowboy movies. But it’s got Guy Madison in it, which counts for a lot, and Patricia Medina (The Buckskin Lady, 1957).
Based on a story by special effects genius Willis O’Brien (King Kong), this Mexican co-production finds Madison as a rancher trying to find out why his cattle are disappearing. It’s a shame Willis didn’t get to handle the animation, because the effects are only so-so. He had been shopping this story around for years. It was eventually made a second time as Valley Of Gwangi (1969), with effects by O’Brien’s former student Ray Harryhausen. It’s a fun film, and very cool in CinemaScope.
Hollow Mountain will be paired with The Neanderthal Man (1953) for a 2014 Blu-ray release from Shout Factory. As you may know, Shout Factory has a horror specialty label called Scream Factory. I’d like to propose that they launch an all-Western division — Shoot Factory, perhaps. They take great care in their releases.
