I've been trying to find the name of a movie I remember seeing on TV on several occasions. What I remember of the plot:
- A probe/satellite returns to earth
- It's brought to an underground facility and is studied
- An alien bacteria onboard spreads, taking over the computer, infecting people and growing into a monster (John Carpenter/The Thing style)
- The facility is nuked at the end of the movie to kill it off, but you see the alien escaped the facility, walking off-screen as the bomb goes off.
I've been scouring lists of sci-fi movies to no avail. Sound familiar to anyone?
