Did You Know?

Whereas all of Ray Harryhausen's past films had an "Approved" rating from the Motion Picture Association of America, the modern ratings system was introduced around this time, and this was the first film of his to get a "G" rating.See more »
Revealing mistakes: Gwangi's apparent color 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.See more »

Cowboys vs. Dinosaurs., 18 January 2002
Author: Chris Gaskin from Derby, England

The Valley of Gwangi is a lot better than the earlier dinosaur/cowboy movie, The Beast of Hollow Mountain. It contains a lot more dinosaurs and better special effects. These were created by the great Ray Harryhausen.

The film itself is very enjoyable with good performances from the cast including Richard Carlson (It Came From Outer Space, The Creature From the Black Lagoon). The music score is excellent. The ending was rather sad though.

This is a must if you like dinosaur films like me.

Rating: 4 and a half stars out of 5.
