BEVERLY HILLS, Calif. — Hollywood is in a bleak mood this year, and the Oscar nominees announced Tuesday morning reflected that state of mind.
“No Country For Old Men,” about the ruthless aftermath of a botched drug deal, and “There Will Be Blood” starring Daniel Day-Lewis as a scheming oil man in an epic about American capitalism, took the lead in the Oscar race with eight nominations each, including best picture and best director.
Meanwhile, “Michael Clayton,” a throwback thriller to the 1970s, starring George Clooney as a corporate fixer, received seven nominations, including nods for best picture, best actor (Mr. Clooney) and best supporting actress (Tilda Swinton). “Atonement,” the adaptation of Ian McEwan's time-shifting, betrayal-filled novel, also captured seven nominations, including for best picture and best supporting actress (Saoirse Ronan).
Unlike last year, when flashy mainstream hits like “The Departed,” “Dreamgirls” and “Little Miss Sunshine” dominated, the 2008 Oscar race swings back toward critic-driven films. Many of the movies that received multiple nominations feature dark themes and unconventional endings that, for the most part, have failed to attract broad audiences.
