Answer 2

best adapted screenplay

6.55pm: One of the great delights of this year's Oscars is the chance to hear Helen Mirren announce, in her perfect, cut-glass diction, the full title of Sacha Baron Cohen's Borat movie (though for some reason she pronounces it "B'rat"). She and Tom Hanks are on hand to dish out the award for best adapted screenplay. It goes to William Monahan for his work on The Departed, a remake of the 2002 Hong Kong thriller Infernal Affairs.
