One of my favorite films from the 80's (I've long since lost count of the number of times I've seen it) The Hidden is a science fiction roller-coaster ride starring Kyle MacLachlan and Michael Nouri (and featuring Claudia Christian as a stripper who actually screws someone to death!).
While the original idea of a criminal alien parasite being hunted by another member of it's species dates back at least to Hal Clement's first novel, Needle, The Hidden ramps it up to overdrive. Where Needle largely involves detective work, The Hidden mostly involves crazy car chases, lots of guns, and much in the way of general mayhem.
But it's not just the mayhem which makes this worth watching. Kyle MacLachlan's portrayal of the FBI agent (yes, again!) is particularly entertaining, the dialogue is clever, and, of course, the basic concept is pretty damn cool.
I can't recommend this one enough. While a little dated, it's worth watching for the first 10 minutes alone.
