You know, Idris Elba does a superb job in Mandela. Colin Firth in the Railway Man, Robert Redford, too. (who, IMO is the favorite) So the Best Actor nominees aren't necessarily a lock. Of course there's Leo for two movies, where he plays versions of Gatsby.
Yes, I believe Matthew Mc Conaughey will get a look see, I believe that Christian Bale for American Hustle will get checked out, and of course Hanks will be considered, as will Chiwetel Ejiofor, and Forrest Whitaker. Don't forget Joaquin Phoenix. I hear he's wonderful in "Her."
Some people are even kicking Hugh Jackman's name around, and if this were a weak year for male leads I'd say sure, but he played an over wrought father. (yawn.)
Best Supporting? Again, look at American Hustle, look at Jared Leto, Josh Brolin, possibly Javier Bardem, certainly Clooney, whether he deserves it or not, and possibly Ewan McGregor because he is well liked and always good.
Then we have any one of several actors from The Butler, Fassbender from 12 Yrs. a Slave, and Paul Dano is a real long shot, but worth considering. Maybe even Jonah Hill for Wolf of Wall Street. Is James Franco promoting himself for Spring Breakers in the Best Supporting Actor category or for Lead?
As for leading women, Meryl for August Osage County, Cate for Jasmine, Sandra Bullock and Judith Dench for Philomena. Possibly Lupita from 12 years. Amy Adams, Kate Winslet might get considered, and so might Nicole Kidman.
Supporting Actresses: Julia Roberts, Oprah Winfrey, Melissa Leo, and Scarlett Johannson for Her. Can't think of who else.
