Yes, you can't go by anything at the imdb. For example, most of the MGM/UA DVD things were 1.66 - just something they did back in the day and have never changed. So, let's say some person saw that, assumed it was correct, they go onto an imdb page and put that in and there it stays...
That is, of course, completely untrue. The film was shot for and shown in 1.85 - by the year this film was made 1.85 was the non-scope standard and that's how this film played. And as I've written elsewhere, this is one of the best MGM/UA transfers.
