Movie Night No. 14 is for Sir Christopher Lee, and considering last year we took a look at him starring in a version of Jekyll & Hyde called I, Monster, it makes sense to back up to a Hammer production in which he plays the "friend." This was directed by Terence Fisher, who directed a slew of Hammer films, including Curse of Frankenstein and their Dracula, which of course had a lot of Lee in them. Look for a short appearance by Oliver Reed in this as well.
The film is available on DVD as part of the Hammer Icons of Horror Collection.
