It's driving me nuts. I remember I sci-fi horror-esque movie I watched as a kid. I think it's a group of explorers who land on a deserted planet, where they find a large container filled with a black substance. The container cracks, in its turns out this substance is sentient, and begins taking over members of the crew, and they subsequently seek to murder everyone else.
It's was dark, creepy, and suspenseful and I loved it. However for the life of me, I can't search for it on the internet, because the only thing that come up are Alien (for obvious reasons), The X-Files (The Black Oil), Spider-Man (Venom), and Men In Black (for more obvious reasons).
Anyone have a clue? At all? I'm pretty sure it was made in the 80's, but even that I can't be sure of.
