A cowboy named Tuck Kirby seeks fame and fortune by capturing an Allosaurus living in the Forbidden Valley and putting it in a Mexican circus. His victim, called the Gwangi, turns out to have an aversion to being shown in public.
In 1971, Warner Brothers cleverly reissued this film in the USA on a double bill with When Dinosaurs Ruled the Earth (1970).
Gwangi's apparent color, as well as the color of the other creatures, changes several times over the course of the movie because there was so much animation to do that Harryhausen did not have enough time to do proper color testing. Gwangi ranges from gray to violet to purple from one scene to the next.
In the closing credits cast list, Order #10 is GWANGI
Many local TV stations delete the scene in which Gwangi, the allosaur, kills a circus elephant, claiming the scene depicts cruelty to animals.
