Dr Marlowe (Christopher Lee) is a follower of the ideas of Freud and has developed a serum which can remove inhibitions. The first person he tries it on, a young woman, removes all of her clothes. For some reason Marlowe decided to continue his experiments on himself. He becomes a craved vicious thug with a deformed face who haunts the streets of Old London Town called Mr Blake...
Marlowe's friend Utterson (Peter Cushing) is starting to suspect things are not right with Marlowe. As for the Doctor, prolonged use of the serum begin to push him over the edge and out of control...
This is a good version of Jekyll & Hyde, with the Victorian feel down to a tee. Christopher Lee gives his usual excellent performance in a British horror of the period though the film falls short of being truly great. The action is often a bit static and Cushing could have done with more of a role.
