I've also heard that fans who were lucky enough to get tickets for the Oprah show taping tomorrow will get a screening of the movie tonight. Not sure if that's true or not, but I imagine if they see anything it won't be the full movie. Highly doubtful that anything will be leaked--apparently Oprah is really, really strict as far as cameras and phones are concerned.
Will update as new info is available.
Be careful what you read and believe--I know a lot of people are making special travel plans for the premiere. Don't buy anything (tickets, hotel rooms, etc) until there's official word from Summit.
That's my friendly PSA for the afternoon. ;-)
