(I can't believe I got up for this. I was all like, "Whatever, they'll be still there when I get up, they don't self-destruct in five seconds," and then I woke up at 6:50 without even meaning to anyway.)
ETA: So. Robert Downey Jr. and Heath Ledger both got Supporting Actor nominations; Kate Winslet only got nominated for lead; big cheers in the auditorium for Melissa Leo for Best Actress and Michael Shannon for Supporting Actor; Benjamin Button had a surprisingly (I thought) strong showing; and your five Best Picture nominees are The Curious Case of Benjamin Button, Frost/Nixon, Milk, The Reader, and Slumdog Millionaire. AwardsDaily, if you can get through, has typed up the list of the categories we know.
ETA: WHERE IS THE COMPLETE LIST? I WANT TO KNOW ABOUT THE COSTUMES!
ETA: THE LIST IS ON THE MAIN OSCAR.COM PAGE BUT NOT ON THE NOMINEES PAGE. WHY ARE PEOPLE STUPID. Wait, are there really just three songs nominated, and two of them from Slumdog Millionaire?
ETA: IMDB has a list you can actually read. There really do seem to be only three songs. Snap.
