What really annoys me about Peter Hyams (and this is in all his movies I saw) is the constant fog. There's always some smoke on the set. I'd be seriously rattled to wake up inside a smoke-filled spaceship around Jupiter.

But I like the touch of Curnow holding Maxim's hat. Their relationship is never mentioned in any other place in the movie. It was a nice touch (even though Max doesn't die in the book).

There is a good comparison of both Discovery's at http://2010odysseyarchive.blogspot.com/2016/03/2001-versus-2...
