PSA: the turtleneck guy in Plan 9 from Outer Space was Bela Lugosi's chiropractor, and that's why he covers his face
We watched Plan 9 from Outer Space at my buddy's place in Akron on Saturday and I looked up the cast after. Bela Lugosi died before filming started, so Ed Wood used test footage of him and had his wife's chiropractor, Tom Mason, fill in. Mason was about 6 inches taller and way younger, so he hides his face behind his cape the entire time. I rewound to check and you can see the height jump between shots clear as day. What other movies have a stand-in that obvious once you know to look?
