And they're off!

The race to awards season has officially begun, with the Screen Actors Guild yesterday announcing nominations for its 20th annual SAG Awards, which take place Jan. 18.

In the movie categories, "12 Years a Slave" led the pack, with noms for actors Chiwetel Ejiofor, Michael Fassbender and Lipita Nyong'o, as well as the entire lot of actors for Best Cast of a Motion Picture.

Competing against "12 Years" for the night's top honor are the flicks "American Hustle," "August: Osage County," "Dallas Buyers Club" and "Lee Daniels' The Butler."

Ejiofor's competition for lead actor are Bruce Dern ("Nebraska"), Tom Hanks ("Captain Phillips"), Matthew McConaughey ("Dallas Buyers Club") and Forest Whitaker ("The Butler."). Noticeably snubbed was Robert Redford for his impressive turn in "All Is Lost."

Meanwhile, the nominated leading ladies in film are Cate Blanchett ("Blue Jasmine"), Sandra Bullock ("Gravity"), Judi Dench ("Philomena"), Meryl Streep ("August: Osage County") and Emma Thompson ("Saving Mr. Banks.")

SAG also awards the best in the year's television acting, with AMC's "Breaking Bad" and NBC's "30 Rock" coming out on top, nom-wise.

Nominations for the Golden Globes will be announced today.
