History Film / TheBeastOfHollowMountain

* DiabolusExMachina: The titular beast. The film is a typical generic Western for the first three quarters, and then, out of nowhere, a dinosaur attacks.

* HesJustHiding: In-universe: Panchito adamantly refuses to believe that [[spoiler: his father is dead and goes into the Hollow Mountain in search of him]]. It nearly results in him being killed by the dinosaur.

* DevelopingDoomedCharacters: Much like fellow ''Series/MysteryScienceTheater3000''-riffed movie ''Film/{{Avalanche}},'' the movie is mostly spent on introducing the characters and their relationships with each other before the eponymous beast actually appears in full in the last act. In fact you could cut the monster out ''entirely'' and the only plot hole would be how Enrique died.

* DevelopingDoomedCharacters: Much like fellow MST3K-riffed movie ''Film/{{Avalanche}},'' the movie is mostly spent on introducing the characters and their relationships with each other before the eponymous beast actually appears in full in the last act. In fact you could cut the monster out ''entirely'' and the only plot hole would be how Enrique died.

* LeftHanging: The movie abruptly ends after the defeat of the dinosaur, with no details about what happened to the surviving main characters [[spoiler: (such as Jimmy, Sarita, or Panchito)]] afterwards, or how the people back in town react to [[spoiler: Enrique's death]] or even if Panchito ever accepted [[spoiler: his father's death]].

* NoEnding: The movie abruptly ends after the defeat of the dinosaur, with no details about what happened to the surviving main characters [[spoiler: (such as Jimmy, Sarita, or Panchito)]] afterwards, or how the people back in town react to [[spoiler: Enrique's death]] or even if Panchito ever accepted [[spoiler: his father's death]].

* CaliforniaDoubling: Subverted - while the film is clearly shot quite cheaply, it was actually shot in Mexico.

* HesJustHiding: Panchito adamantly refuses to believe that [[spoiler: his father is dead and goes into the Hollow Mountain in search of him]]. It nearly results in him being killed by the dinosaur.

* TyrannosaurusRex: What the eponymous beast turns out to be.

* WidowedAtTheWedding: Sarita begs Jimmy to leave town because she knows the fued between himself and her fiance Enrique will only end with one of them dead, and she explicitly states she doesn't want to be "widowed on [her] wedding day." [[spoiler: Which happens anyway thanks to the titular monster!]]

Amidst rumors that the eponymous mountain outside a small village in Mexico may be cursed as farmers and their cattle never return from it, American rancher Jimmy Ryan (Madison) butts heads with the hard-headed Enrique (who believes that Jimmy is trying to steal away his fiance, Sarita), pals around with fellow rancher Pancho and his son Panchito, and attempts to solve the mystery of why people and animals who wander into Hollow Mountain never seem to return. He and his friends eventually discover that a Tyrannosaurus Rex lives , and havoc ensues.

This movie was featured in the fifth episode of the reboot of ''Series/MysteryScienceTheater3000''. Tropes pertaining to said episode can be found [[Recap/MysteryScienceTheater3000S11E05TheBeastOfHollowMountain here]].

* TheAlcoholic: Pancho "drinks to forget his wife"... but it's likely he'd drink anyway. This is played for jokes.

* DevelopingDoomedCharacters: Much like fellow MST3K-riffed movie ''Film/{{Avalanche}}'', the movie is mostly spent on introducing the characters and their relationships with each other before the eponymous beast actually appears in full in the last act.

* DeathOfTheHypotenuse: While it's hardly uncommon for a western LoveTriangle to end with one of the competitors dying, this film is the first to have one of them ''[[spoiler: choked to death by a dinosaur.]]

* WeirdWest: An early entry in the genre, and the first to feature a dinosaur.

* CorruptBusinessman: Enrique is willing to do anything to undermine Jimmy's business. Even when he actually wins and Jimmy plans to leave town at Sarita's insistence, he still tries to cause a stampede to steal Jimmy's cattle.
