Dr Jekyll and Sister Hyde.
Dr Jekyll(Ralph Bates) is a very dedicated scientist chap who gets depressed when he realises that death will end his scientific discoveries. so decides to find an elixer of life, which requires grave robbing with the help of Burke and hare and knocking off the local hookers. and when he does discover the elusive elixer, there's just one snag, it turns him into a foxy lady who enjoys making red dresses out of the curtains.
this is one of Hammer's greatest films from the 1970's period. It is very good indeed and has a great story, bags of 1800's atmospheres in the foggy streets and marvellous performances from Ralph Bates as the crazed Dr Jekyll who does what ever takes in the name of science. and Martine Beswick who is brilliantly cast as the lusty and evil Mrs Hyde who continues with Dr Jekyll's cull of the local whores after he tries to stop, even keeping a trusty blade in her boot.
A love interest is also providing by Susan Brodrick who plays Dr Jecyll's prim and proper neighbour who has the hots for Mr Bates.
top notch Hammer film indeed with plenty of black comedy as well and suspenseful kills. 90 out of 100.
