The actors' branch is the largest at the Academy of Motion Pictures Arts & Sciences, and almost all of those voting members also vote for the Screen Actors Guild Awards.

While Halle Berry received a Golden Globe nomination for her work in 'Frankie and Alice,' she was left off the list when nominations for the 17th SAG Awards were announced.

Berry was one of many actors who were snubbed, but one of the biggest omissions, as noted by The Film Experience's Nathaniel Rogers, is among the films nominated for Outstanding Performance by a Cast in a Motion Picture. Yaya DaCosta and Rashida Jones were left off the ensemble list from their respected films, 'The Social Network' and 'The Kids Are All Right.'

"Yaya DaCosta, who so deliciously handles her role of Ruffalo's lover and employee. Seriously now, she delivers fantastic line readings in this movie and underlines some of the movie's more subtle points about Ruffalo's character as well as contributing to its randy high spirits. I consider it an egregious omission," states Rogers.

While 'The Social Network' has an abundance of cast members, Rashida Jones, who plays Zuckerberg's attorney, is in a good portion of scenes and should have been included.
