The frontrunners for acting so far, and this could change a lot, are the following:
Best Actress: Jennifer Lawrence for Silver Linings Playbook
Best Actor: Joaquin Phoenix for The Master and Daniel Day-Lewis for Lincoln
*I'd have to give Phoenix a slight edge. It'd be DDL's third Oscar, a rarity.
Best Supporting Actress: Anne Hathaway for Les Miserables
Best Supporting Actor: Phliip Seymour Hoffman for The Master
For Best Picture, there's Argo, Silver Linings Playbook, Les Miserables, Lincoln, The Master, Life of Pi...
It should be interesting. There are more possible nominees this year who could get a third Oscar: Daniel Day-Lewis, Robert De Niro, Sally Field, and Phlip Seymour Hoffman could get his second. I really wish Amy Adams would win Best Supporting Actress, but it seems like she's the third most-touted performance, and I don't know if there's ever been a movie where Best Actor, Best Supporting Actor, and Best Supporting Actress all came from the same movie. I know "Streetcar Named Desire" and "Who's Afraid of Virginia Woolf?" had actress and the supportings.
