A couple of major Oscar contenders had the write stuff Saturday night.

Brokeback Mountain and Crash scored the top prizes at the 58th Annual Writers Guild of America Awards, firmly establishing them as the favorites for the screenplay Academy Awards.

Brokeback Mountain scribes Larry McMurtry and Diana Ossana lassoed the award for Best Adapted Screenplay for their drama about a couple of cowboys carrying on a secret love affair. They adapted a short story by Annie Proulx that was first published in the New Yorker.

With its latest victory, the Ang Lee-directed Brokeback racked up a leading eight Oscar nominations, including Best Picture, Best Director and Best Adapted Screenplay. The film already corralled Best Picture, Director and Screenplay at this year's Golden Globes and topped both the Directors Guild and Producers Guild Awards, as well as several key critics groups.

Crash, a film about race relations in Los Angeles that's up for six Oscars, earned the Best Original Screenplay trophy for Paul Haggis and Bobby Moresco. The story was dreamed up by Haggis, who won a Best Adapted Screenplay Oscar last year for Million Dollar Baby.

Earlier in the week, Alex Gibney received the Documentary Writing Award for Enron: The Smartest Guys in the Room.

On the tube side, the scribes behind ABC's survival adventure drama Lost took home the award for Best Dramatic Series trophy, while Best Comedy Series went to Larry David for HBO's Curb Your Enthusiasm. ABC's rookie medical drama Grey's Anatomy picked up Best New Series. Late Night with Conan O'Brien won Best Comedy/Variety Series.

Fox's House earned Best Episodic Drama for an installment titled "Autopsy," while Showtime's Weeds scored Best Episodic Comedy for "You Can't Miss the Bear." Best Animated Episode went to Fox's The Simpsons for an episode by writer Michael Price titled "Mommie Beerest."

Two HBO TV movies also scored. Warm Springs, about Franklin Delano Roosevelt's struggles with polio, won Best Long-Form Original, and The Life and Death of Peter Sellers, based on a book by Roger Lewis, garnered Best Long-Form Adapted.

Special achivement honors were given to George Clooney and Grant Heslov, who were bestowed the Paul Slevin Award for their Oscar-nominated script to Good Night, and Good Luck, and Al Jean and Michael Reiss, who were handed the Animation Writers Caucus Animation Award. Earning Laurel Awards for their work on the big and small screen, respectively, were writer-director Lawrence Kasdan (The Big Chill, Raiders of the Lost Ark, The Empire Strikes Back) and veteran TV producer Stephen J. Cannell (The A-Team, The Rockford Files, Hunter).

The WGA Awards are voted on by the guild's 11,500 members and are held simultaneously in Beverly Hills and New York. The guild award is considered a reliable Oscar predictor.

Last year's big winners, Charlie Kaufman, who won for his original script for Eternal Sunshine of the Spotless Mind, and Alexander Payne and Jim Taylor, who won Best Adapted for Sideways, repeated at the Academy Awards.
