This isn’t a Hammer film but in the same tradition with great performance by Hammer regular Hazel Court. Color is vivid and Welsh location well presented. Camera operator is the great Nicholas Roeg who later became a cinematographer and director. Movie has reputation for gore but only for its early 60s period. There is a shot in last third of movie showing surgically open chest cavity and beating heart. It is a convincing effect.
I always wanted to see this movie again and now I have it, good color, good acting, good directing and very well done blu-ray transfer. all in all a good flic for it's age.
