Did I get a bad disc or why didn't they fix the frame towards the end of the movie when they are heading back to earth and Leslie is holding Anne, it appears to jump or twitch for a second. Even in the supplements, when that particular clip came up, it did the same thing. Other than that, the presentation is great. Looks a lot better than the old disc. This is my favorite sci-fi movie because I was impressed with it when it was first shown theatrically. I absolutely agree, this disc is highly recommended!!!!!
