ABC's hit series "Lost" and "Desperate Housewives" won top acting honors for television at the Screen Actors Guild Awards this Sunday. The "Lost" cast won the best ensemble performance award for a dramatic television series while "Desperate Housewives" received the ensemble award for best comedy series.

Felicity Huffman was named best actress in a comedy series for her role as one of the "Desperate Housewives." She is also a contender for best actress for her work in the film "Transamerica," in which she plays a man on the verge of completing a sex change operation.

British actress Rachel Weisz won best supporting actress for her role as the doomed activist wife of a British diplomat in "The Constant Gardener," Sandra Oh was named best actress in a television drama for her work as a fledgling doctor in "Grey's Anatomy" on ABC, while Kiefer Sutherland was named best actor in a dramatic series for his work as a U.S. agent out to outwit terrorist plots in "24" on Fox.
