As we say in the South, "Bless his heart." Director Joel Bender [Mighty Morphin' Power Rangers: The Movie] set out to make a serious horror film in 1989. He failed quite spectacularly. It's too bad because The Immortalizer has a great concept behind it: Old wealthy clients pay the doctor loads of cash so that their brains can be transplanted into young, nubile bodies. It would have made a great episode of Tales from the Crypt but here the story feels like its been stretched to the breaking point and beyond. Furthermore, it might have actually worked if the movie had a sense of humor. Unfortunately, it doesn't and tries to pass itself off as genuine horror. Too bad.
The Immortalizer is also hampered by marginal acting and a terrible soundtrack. Yes, it's true they had a limited budget to work with but other directors over the years have proven that money isn't everything. You can make a great horror film on a shoestring budget [Night of the Living Dead, anyone?] but this is not one of them.
To add insult to injury the surgical science in this film is groan worthy. There are so many problems with it I simply don't know where to start. The funniest gaffe is that once the surgery is done the young body speaks with the voice of the old brain. This makes no sense whatsoever considering they now have new vocal chords, etc.
As a final groan, the "ghouls" or whatever they're supposed to be look like local wrestlers with really bad store bought make up. They evoke no sense of terror whatsoever and their constant growling gets downright irritating pretty quickly.
The Immortalizer is not as bad as IMDB says it is, but it's not good either. There are so many wonderful horror films to see that were made in the 1980's. I don't see why anyone should spend their time watching this one.
