You know a movie is either going to suck or a celebrity has some kind of issue which will turn up in the tabloids later if you walk out of your own premiere. Many celebrities walk a red carpet and then never walk into the theatre or walk quickly through it and wait for the after party. But, if they do sit down, they usually stay. Hugh Laurie could not be bothered. At the premiere for his movie The Oranges, it started late because the red carpet line was taking longer than usual. So, Hugh got up and walked out. His reps said he was exhausted and others said that he was hungry and others said he had a prior commitment. So, yeah, they were all shocked and had no idea what to say.
