2012 Screen Actors Guild Awards

The biggest and brightest stars of film and television came together on Sunday, Jan. 29 to honor their peers at the 18th annual Screen Actors Guild Awards.

Christopher Plummer and Octavia Spencer took home the evening's first awards for supporting actor and actress, while Alec Baldwin, Kate Winslet, Betty White and the casts of Modern Family and Boardwalk Empire were among the others earning nods during the ceremony. Receiving the night's top honors were Jean Dujardin for best actor in a leading role, Viola Davis for best female actor in a leading role and The Help for best ensemble in a motion picture.

Mary Tyler Moore accepted the Lifetime Achievement Award from Dick Van Dyke midway through the show, taking the opportunity to explain why she chose to use her middle name to separate herself from the six other Mary Moore's already on SAG's roster in the early stages of her Hollywood career.
