Corridors of Blood (1958)

A lot of fun watching two great horror icons together like Boris Karloff and Sir Christopher Lee. I'm so glad The Criterion Collection bothered putting this foursome out in their 'Monsters and Madmen' boxed set. Such a guilty pleasure to behold, in its intriguing period-piece script of a well-meaning doctor trying to discover anesthesia yet getting drug-addicted in the process. Great stuff.
