Actors honored their own at the Screen Actor’s Guild Awards last night, with top nods going to Oscar nominees Russell Crowe, for his performance in “A Beautiful Mind,” and Halle Berry for “Monsters Ball.” Along with those two, the star-studded “Gosford Park” ensemble won for cast performance. Sir Ian McKellen and Helen Mirren took the supporting actor and actress awards for their work in “The Lord of the Rings” and “Gosford Park,” respectively. The awards show season, which culminates in the Oscars, hits its highest gear with the SAG awards, which often are an Academy Awards indicator. This year the SAG awards have simply fueled the fires of speculation, as nominees “In the Bedroom,” “Moulin Rouge,” “Gosford Park” and “The Lord of the Rings” and their cast members have shared the numerous industry and critics’ awards. The 98,000 members of SAG also honor television. “The West Wing” swept the drama category for the second year in a row, with costars Allison Janney and Martin Sheen taking best actor and actress and the whole cast getting the best ensemble acting nod. In comedy, Megan Mullally and Sean Hayes both won for their work on “Will & Grace,” and the cast of HBO’s “Sex and the City” won for best ensemble. The Lifetime Achievement Award went to Ed Asner, best known for his work on “The Mary Tyler Moore Show” and “Lou Grant.” The Oscars will air on March 24 on ABC.
