I rented "Myra Breckinridge" from the library and I knew from about 10 minutes in that it was going to be a total disaster. I had seen scenes of it on YouTube so it looked like it would be good. The Mae West scene when she's interviewing studs and Tom Selleck is one of the studs. And Mae was in her campy way the best part of the movie, she had a few good one-liners, but the rest of it was painful torture.
What are some other movies that you thought, based on what you knew about it before, that you thought you'd like than turned out to be complete turkeys?
