After Raquel Welch conquered the screen in One Million Years B.C., Hammer Studios followed up with When Dinosaurs Ruled the Earth, written and directed by Val Guest (The Quatermass Xperiment) and based on a story by J.G. Ballard (Crash). Victoria Vetri stars as Sanna, rescued from ritual sacrifice by Tara (Robin Hawdon), a member of a rival tribe. Her survival coincides with the mysterious formation of a new “fire” in the sky: the moon! Sanna’s old tribe blames her for this affront to the sun; Sanna flees their wrath and Tara follows. Their shared adventures loom as large as the giants who once ruled the earth!
