LOS ANGELES -- "No Country for Old Men" solidified its Academy Awards prospects Sunday by taking overall cast honors alongside Javier Bardem's supporting-actor prize at the Screen Actors Guild Awards, which may stand as the highlight of Hollywood's film-honors season if the writers strike undermines the Oscars.

Past Oscar winners Daniel Day-Lewis of "There Will Be Blood" and Julie Christie of "Away From Her" won the lead-acting honors, also giving them a boost to win the same trophies at the Oscars. Day-Lewis dedicated his win to Heath Ledger, the 28-year-old Australian actor who was found dead in his Manhattan loft last week.

"In 'Brokeback Mountain,' he was unique, he was perfect," said Day-Lewis, already an Oscar winner for "My Left Foot." "That scene in the trailer at the end of the film is as moving as anything I think I've ever seen."

Actors bid fond farewell to one of TV's most-acclaimed series ever as "The Sopranos" swept the dramatic categories, grabbing the lead-acting honors for James Gandolfini and Edie Falco and, minutes later, the overall cast award.

Bardem had kind words for Joel and Ethan Coen, who directed "No Country" and adapted the screenplay from Cormac McCarthy's novel.

"Thank you, guys, for hiring me, and thank you for taking the hard work of choosing the good takes instead of the ones where I really sucked," said Bardem, who won for his chilling role as a relentless killer tracking a fortune in missing drug money.

Ruby Dee won supporting actress for "American Gangster." She shared fond thoughts of her late husband and frequent acting partner, Ossie Davis, who died in 2005.

"I accept it also for my husband Ossie," the 83-year-old Dee said, "because he's working on things up there."

Though its last episode aired several months ago, "The Sopranos" grabbed all three TV drama categories to open the ceremony.

"Ten years ... I wish for everybody in every walk of life, but particularly for actors, to have the opportunity to have a work experience like I have had with my family here," Falco said. "You're not supposed to get this attached because it's a transient business. I have fallen in love with these people and I don't know how you walk away from that."

For comedy series, Alec Baldwin and Tina Fey were the lead-acting winners for "30 Rock," while "The Office" won for best ensemble.

The obligatory package of clips to honor stars who died in the past year took on more immediacy, ending with a moment from "Brokeback Mountain" featuring Ledger. The cause of his death had not yet been determined.

The guild presented its life-achievement award to Charles Durning, whose credits include "The Sting," "Tootsie" and "O Brother, Where Art Thou?"

"There's nothing more gratifying than having an achievement award from one's peers," Durning said. "Over 50 years ago, I had the honor of working with some of the best actors, directors and writers in our industry. It's been a dream come true."
