Nominees for the 18th Annual Screen Actors Guild Awards for outstanding performances in 2011 in five film and eight primetime television categories and for the SAG honors for outstanding action performances by film and television stunt ensembles were announced this morning in Los Angeles at the Pacific Design Center's SilverScreen Theater in West Hollywood.

SAG President Ken Howard introduced Judy Greer (The Descendants) and Regina King (TNT's Southland and the 18th Annual Screen Actors Guild Awards Social Media Ambassador) who announced the nominees for this year's Actors®. SAG Awards Committee Chair Jo Beth Williams and Vice Chair Daryl Anderson announced the stunt ensemble nominees.

The 18th Annual Screen Actors Guild Awards will be simulcast live nationally on TNT and TBS on Sunday, Jan. 29 at 8 p.m. (ET)/5 p.m. (PT) from the Los Angeles Shrine Exposition Center. An encore performance will air immediately following on TNT at 10 p.m. (ET)/7 p.m. (PT). Recipients of the stunt ensemble honors will be announced from the SAG Awards red carpet during the TNT.tv and TBS.com live pre-show webcasts, which begin at 6 p.m. (ET)/ 3 p.m. (PT).

Of the top industry accolades presented to performers, only the Screen Actors Guild Awards are selected solely by actors' peers in Screen Actors Guild. Two nominating panels-one for television and one for film-each composed of 2,100 randomly selected Guild members from across the United States, chose this year's Actor® and stunt ensemble honors nominees. Integrity Voting Systems, the Awards' official teller, mailed the nominations secret ballots on Wednesday, Nov. 23. Voting was completed at noon on Monday, Dec. 12, 2011.

The complete list of nominations for the 18th Annual Screen Actors Guild Awards follows. A replay of both announcements will be available for viewing on TNT.TV and TBS.COM.
