John Wells' dysfunctional family adaptation "August: Osage County," which hits theaters Dec. 25 and features an all-star cast including Meryl Streep and Julia Roberts, also picked up awards-season momentum with three nominations, including outstanding performance for the cast.
The SAG nominations are one of Hollywood's first major announcements on the long road to the March 2 Oscars. The Golden Globe nominations will be revealed Thursday morning.
Joining the SAG list for outstanding cast performance are Jean-Marc Vallee's AIDS drama "Dallas Buyers Club" and the sweeping White House servant tale "Lee Daniels' The Butler." Both films topped the list with three nominations each.
Also nominated for cast performance was David O. Russell's 1970s con-artist romp "American Hustle." And the film scored an individual supporting nomination for Jennifer Lawrence.
"12 Years a Slave" also attained individual acting nominations, including male lead for Chiwetel Ejiofor as a displaced free African-American man, Michael Fassbender for supporting actor as a ruthless slave owner and Lupita Nyong'o for female support as a favored fieldworker.
"Osage County" had individual nominations for Streep for female lead as the conflicted matriarch in the adaptation of Tracy Letts' Pulitzer Prize and Tony-winning play, and Roberts as the domineering daughter for supporting female actor.
