Adding to its list of honors, "Brokeback Mountain" scored again by taking the top prize Sunday at the 15th annual Producers Guild of America Awards.

Diana Ossana and James Schamus, who produced the Ang Lee-directed story of two ranch hands who conceal an ongoing homosexual affair from their families, took home the guild's top prize, the Darryl F. Zanuck producer of the year award.

Ossana also co-wrote the screenplay with famed Western author Larry McMurtry.

"Brokeback" won four Golden Globes last week — including best picture honors in the drama category — and has been lauded by critics' groups around the country.

The man-and-dog buddy adventure "Wallace & Gromit: The Curse of the Were-Rabbit" earned Claire Jennings and Nick Park the producer of the year award for animated film.

Other winners at the awards ceremony held at the Universal Hilton included:

• Long-Form Television: "The Life and Death of Peter Sellers," HBO.

• Episodic Drama: "Lost," ABC.

• Episodic Comedy: "Entourage," HBO.

• Variety Television: "The Ellen DeGeneres Show," Syndicated.

• Non-Fiction Television: "60 Minutes," CBS.
