I have been racking my brain for years on which apparently is a very forgotten alien movie that I have googled, and googled...So apparently it must be a rarity. It had to have come out between 1995 and 2000, but I believe it was more so 1998 - 2000 to narrow it down more. I remember a small crew investigating a strange alien spaceship, and all of the aliens being dead except the one in the control center of the ship where it appeared dead, but wasn't. Its brain was still somehow alive and controlling the spaceship through the equipment it had on its head. The two remaining crew survivors try to take the control equipment over from the alien. The aliens looked a bit like the bad gremlins do after they mutate into their worst state. I can't find it anywhere! Does it jog anyone else's memory? It is older. Back in 1999 or 2000, I was at a sleepover and the adults had it on. It was so long ago that I can't remember it clearly enough to find it easily. I believe it is one of those lost films that didn't get enough attention.
Is it possible that this was the TV version of Steven King's "The Tommyknockers"? The alien spaceship was buried under the earth near a small town. The aliens' technology drained life energy from people and converted it to psionic energy to power the ship and then back to life energy to regenerate the crew. Jimmi Smits sacrificed himself to save the town by donning the control headpiece and launching the ship to it's destruction.
