Set during the era of the Wild West, VALLEY OF GWANGI (1968), sees cowboys from a Wild West Show trying to capture an Allosaurus, known locally as Gwangi ("The Terrible One"), so they can exhibit it. Although they capture the beast, it soon escapes and starts to terrorise the local population. Desperately they seek a way to deal with the monster once and for all. This western contains amazing (for the time) effects from the master of stop motion animation, Ray Harryhausen.
