When I first watched this, some 4 years ago, I remember being very disappointed with it and recall labeling it a lazy overall effort, especially as it heavily borrowed footage not only from the previous film - THE MUMMY'S HAND - but also FRANKENSTEIN (1931), BRIDE OF FRANKENSTEIN (1935) and THE WOLF MAN (1941) for its mob scenes at the climax! However, coming back to it now - and despite having just watched the other "Kharis" films - I found it to be quite enjoyable, atmospheric and competently handled (especially during Chaney's various rampages and the fiery finale). It was nice to see Dick Foran, Wallace Ford and George Zucco (why on Earth did he wait 30 years to exact his revenge?!) reprise their roles from THE MUMMY'S HAND, if only briefly, as it was to have Mary Gordon - Mrs. Hudson of Universal's contemporaneous "Sherlock Holmes" series - as one of Chaney's victims. As for Chaney himself, I thought that his first stab at the role wasn't bad at all: suitably brutish when required but with a hint of emotion seeping through the wrappings on occasion to provide a balance (especially when Turhan Bey, yet another misguided High Priest of Karnak, is liable to jeopardize their 'mission' of restoring Princess Ananka to life by conveniently falling for leading lady Elyse Knox).
