Not a bad science-fiction/horror/gangster genre merge here - utilizing the cutting savvy of two Universal legends, Boris Karloff and Bela Lugosi.
"Black Friday" is a disheveled take on the Jekyll and Hyde story, about an English professor who is run down by a speeding car during a mobster shoot-out. His best friend, a scientist, performs an illegal brain transplant(ation) - stuffing the criminal brain into his dying buddy. During his recuperation, the professor begins exhibiting behavior and specific memories belonging to the notorious gangster. After Karloff learns that the gangster had stashed $500,000 somewhere in the city, he decides to use his friend's transformation in order to get his hands on it...
Again, "Black Friday" is an entertaining flick, though I didn't understand the whole 'face changing' thing. I could buy the fact that the outlaw brain causes him psychological differences, for the sake of the movie, but his changing appearance to some random dude lost me... Was there some kind of voodoo spell cast on him off screen? I could've used a little more explaination on that end. Aside from that, Karloff is typically bad-ass and Lugosi - though equally bad-ass - was very underused. It's an incredibly jumbled flick, but you could do worse.
