And here’s a short magazine blurb on Galaxy of Terror. The man squatting next to the pyramid is Robert Skotak. The two also worked together on Battle Beyond the Stars and Escape from New York, and Cameron later hired Skotak as visual effects supervisor for Aliens, The Abyss, Terminator 2: Judgement Day, and Titanic.
Cameron remembers his friends, I’ll give him that, and Aliens is the greatest sci-fi action movie ever made.
