In the category of Best Adapted Screenplay Oscar for repeating the same nominees in the category of the Oscar for Best Picture has Milk than competing in the category of the Oscar for Best Original Screenplay, making a victory here for either a these films could be an indication of what would be the winner of the night. A victory of any film in this section more in the Oscar for Best Editing is the final confirmation of the film would be to give it the Oscar for Best Picture.
I think the film is going to win is The Curious Case of Benjamin Button is an adaptation from a short story by F. Scott Fitzgerald, the author of The Great Gatsby.
The second film with options is that Slumdog Millonaire win here would be a candidate for an Oscar for Best Film.
As for Frost/Nixon, The Reader and Doubt, have few options to take the prize.
