SAN FRANCISCO -- The love story "Brokeback Mountain" won three major awards, including Best Picture and Best Director, from the San Francisco Film Critics Circle, the group announced Monday.

Based on the short story by Annie Proulx, "Brokeback Mountain" chronicles a lifelong romance between two cowboys who first meet as young men herding sheep in 1960s Wyoming. The film, which opened in limited release last week, was directed by Ang Lee and stars Heath Ledger and Jake Gyllenhaal. Australian actor Ledger, previously best known for lighter films like "A Knight's Tale," showed heartbreaking range in the part of Ennis Del Mar, which won him the SFFCC's Best Actor award.

The group honored Reese Witherspoon with its Best Actress award for her sharp and sure portrayal of June Carter Cash in the Johnny Cash biopic "Walk the Line."

Supporting Actor and Supporting Actress awards went to Kevin Costner, for his wry and tender supporting work in the comic drama "The Upside of Anger," and to Amy Adams, who stole the show in "Junebug" as a naive expectant young mother in rural North Carolina.

Best Documentary was awarded to Werner Herzog's "Grizzly Man," which examined the life and death of Timothy Treadwell, an animal rights advocate whose passion for grizzly bears ultimately cost him and his girlfriend their lives.

The complex French thriller "Cache" ("Hidden"), directed by Michael Haneke, took the top prize for Best Foreign Film. "Good Night, And Good Luck," a drama about the feud between Edward R. Murrow and Senator Joseph McCarthy during the 1950s Red Scare, won Best Screenplay for writers George Clooney and Grant Heslov.

The SFFCC gave its Marlon Riggs Award, awarded annually to a member of the Bay Area film community for courage and innovation, to Jenni Olson for her experimental feature "The Joy of Life," which expands the parameters of narrative, documentary and personal cinema while capturing the unique rhythms of life in San Francisco.
