The first film to show dinosaurs and cowboys in the same picture it is notable for being based on a story idea by special effects innovator Willis O'Brien. It used a form of stop motion called replacement animation to bring the dinosaur to life. O'Brien co wrote the script under the pseudonym El Toro Estrella, O'Brien was also to have originally done the special effects for this movie but this did not happen for reasons unknown.
 ProductionThe Willis O'Brien story idea that inspired the basis for his script for this film also inspired his earlier unmade script "The Valley of the Mist" which would later be made as The Valley of Gwangi by O'Brien's protégé Ray Harryhausen.
While the bulk of the stop motion work was done with replacement animation the close ups of the dinosaur were filmed using an articulated puppet.
This was the first film with stop motion effects shot in Wide Screen and color.
