[Fathom Zero]

I need help with finding a movie as well.

It starts off with a man jumping from a cliff, crashing down onto the ground below. A man finds him and does some experiments on him using some sort of micro-organism or bacteria with which brings tissue back to life. He gets better and super-strong and smart and also starts to mutate into some sort of Vampire-looking thing. Bits and pieces start falling off of him. All of this takes place in some sort of Area 51/Underground Complex. Soon, a rescue team comes in because this dude starts killing people. Something goes wrong and everyone is locked in with this guy for a long time. The most important part is that he likes to eat brains. I'd say it was probably from the late 80's to the mid-90's. They may show it late at night on the Sci-Fi channel, occasionally.

Any help would be appreciated.
