"Grey's Anatomy," which won a Golden Globe earlier this month, won the Actor -- the name given to the SAG prize -- for Ensemble in a Drama Series. "The Office" won for best comedy series ensemble.

Hugh Laurie, the star of Fox's "House," won the Actor for best actor in a TV drama, and Chandra Wilson of "Grey's Anatomy" won for best female actor in a drama series. SAG uses "actor" to refer to both male and female performers.

Alec Baldwin of "30 Rock" and America Ferrera of ABC's "Ugly Betty" -- who both won Golden Globes -- were named best male and female actors in comedy series.

Helen Mirren and Jeremy Irons of the HBO series, "Elizabeth I," won for best female and male actors in a TV movie or miniseries.

Mirren won two Actors Sunday night. She was named best female actor in a leading feature film role for her performance as Queen Elizabeth II in "The Queen."
