What exactly do Dave and Frank say, in the lipreading scene?
Despite what some people may like to think, it is, as I understand it, impossible to lip- read from the side, and it would be useless to enlist the aid of a lip- reader to help translate this scene. I refuse to believe that Kubrick would have filmed Dave and Frank discussing football results or other trivia, and Hal’s later conversation with Dave (when Dave is trying to re-enter the Discovery) gives us the best idea of the words that might have passed between Dave and Frank.
