In the
Alien movie, this is the third, and most dramatic change in the
alien creature. One of the unfortunate crew members in the film has recently had the creature removed from his face (
face hugger). The guy has seemingly recovered quite well the next day, but is
quite hungry. He goes to the dining area to have breakfast with the rest of the crew and is
eating like a horse. Suddenly, he spits up his food and grasps his chest- then, a large red explosion bursts from his chest and a small
razor toothed little beast emerges, looks around and runs away.
According to an article in Premiere magazine, leftovers from a meat processing plant were used for the filming of this scene.
