Karloff and Lugosi are the top billed actors in "Black Friday", and Karloff is in fine form (it seems to me that Lugosi is barely in it), but the real reason to watch this movie is for the remarkable dual role played by Stanley Ridges. He's so good at slipping between two entirely different roles (especially with the help of some effective makeup), it's hard to believe the same man is playing both parts.
The plot is standard potboiler "Jekyll/Hyde" fare, but the director zips through it without a lot of wasted time and energy, and the violence is staged effectively without being overly gruesome, so I count this one as a decent choice if you are in the mood for "old school" horror from the 40s and 50s.
