Dir: John Gilling
Starring: Ray Barrett and Jacqueline Pearce
A mysterious doctor keeps his reptilian daughter under lock and key, only for her to start attacking local villagers
This Hammer horror was better than most of the era and is a film of some merit. It features two really good railway scenes, a brief sequence filmed at Loudwater station in Buckinghamshire, and an excellent and wholly unexpected run past of the train from The Titfield Thunderbolt (1953)!!
