I just watched it again for the first time since it came out, and I still remembered a lot of it. O'Toole was terrific. Railsback was very convincing, and even though I've never been a Barbara Hershey fan, I thought she was darned good in this. Yes, I could believe O'Toole's director character was flat out crazy and not just crazy like a fox, and I could believe Railsback really didn't have any idea what was really going on most of the time. I believed what I was supposed to believe, which wasn't necessarily what really was. Great film.
