Oh, the glorious Technicolor! Misty scenes outside are beautiful, cinematography in them is much like those silent films, however, the most of the plot happens in rooms. Anton Diffring is constantly overacting, but this is a good thing - crazy scientists must be overacting to be fun. Story itself isn't interesting and reminds of any other crazy scientist movie of that era.

Good early Hammer picture!

Hazel Court is a stunner and the movie itself is interesting but rather stagy.

"...a must for British horror fans."
