Where he saw it in LA it would not have been mis-framed. You see Goldie's underwear in 1.85 and that's all you ever saw of it in that ratio. He was a kid when he saw it and I'm sure thought he saw more than he saw.
Here's the deal: The film was shot to be projected at 1.85. What your adolescent self saw forty-five years ago is not reliable. I thought Leslie Caron was naked in The Subterraneans when I saw it at eleven. She wasn't.
I'm sorry but what year is this? Wow. Steven Good's post is all you need to know, but the 4x3 open matte is WRONG and the 1.85 is correct just as it's correct for 99% of the films shot since 1954 in this country.
