Unfortunately, I cannot remember much about this film. I must have seen it nearly 10 years ago. It is is black and white, and all I can remember is the scene in which a creature, possibly an alien, is hit by a car driving through a wooded road. The alien walks on all fours, with its joints all bending towards the center of its body. Only one part of the alien is struck by the car.
Maybe the alien came from a meteor?
Sorry guys, that is all I can remember.
