Back in the 1950s, the big family weekend outing would be the drive-in movies. "It came from beneath the Sea", "The Alligator People", "Earth vs the Flyimg Saucers", "1984", "The Dam Busters", "The Four Skulls of Jonathan Drake", "Love Slaves of the Amazons", etc. and (when I was 8 or 9) "The Beast from Hollow Mountain". I finally caught it again on DVR on TCM Thur 27 Jun 2013. For what is billed as the first Cinemascope and Color dinosaur movie, "Beast" has rough goodness.
And it is better than I remember. Surprised me. The dinosaur effects are some what better than "Dinosaurus!" 1960 (apparently the reviewers panning the FX have not seen "Dinosaurus!"), but it is not as good as what Willis O'Brien and Ray Harryhausen did together in Irwin Allen's "Animal World" 1956. I think the "Beast..." FX were billed as RegiScope animation in depth.
I have read that Willis O'Brien's "cowboys and dinosaurs" idea had been kicking around since before his "Mighty Joe Young" another movie where O'Brien and Harryhausen worked together. And after O'Brien's death, Harryhausen decided to make his mentor's unmade pet project as "The Valley of Gwangi".
The dinosaur in "Beast..." appears late and the conflict between the gringo rancher Ryan from Texas and the Mexican rancher Enrique, and the growing romance between Ryan and Sarita, Enrique's betrothed, occupies the first two thirds or three fourths of the movie. Mysterious deaths of cattle are attributed to rustlers and the ranchers' rivalry. But after the steer-chomping Beast makes his appearance, he has lotsa screen time in the last part of the film. (OK, I concede the tongue gets to be a bit much in some scenes. Looks to me like the tongue was rotoscoped onto the sequences shot with replacement animation.)
What has stayed with me from seeing this film over fifty years ago, is the scene where Sarita and the kid Panchito are besieged in a cabin by the Beast. That was scary then, and is still is a moment (or that may be my nostalgia acting up again).
