Surprised there isn't any discussion on this. A lot of it is a fairly 'meh' list, but thumbs up to the academy for the best supporting actor: Heath Ledger in Dark Knight and Robert Downey Jr. in Tropic Thunder both get nominations, alongside academy award stalwart Phillip Seymour Hoffman.
I'm also happy to see Richard Jenkins get a nomination, although I'd be surprised to see him win.
