Joining them among the nominees for best film ensemble cast, the organization's top prize, were the actors of family dysfunction drama "August: Osage County," AIDS drama "Dallas Buyers Club," civil rights tale "Lee Daniels' The

Butler" and 1970s con-artist drama "American Hustle."

The Screen Actors Guild (SAG) awards are among the most-watched honors during Hollywood's busy awards season that culminates with the Academy Awards, which will be given out in March, because actors make up one of the largest voting groups for the Oscars.

The SAG awards will be handed out in Los Angeles on January 18 and shown live on U.S. television networks TNT and TBS.
