Anne Hathaway (The Princess Diaries, Ella Enchanted) and Randy Quaid are joining Ang Lee's gay cowboy love story Brokeback Mountain for Focus Features. Heath Ledger and Jake Gyllenhaal are starring, with James Schamus, Michael Costigan, Diana Ossana, and Larry McMurtry producing. Adapted by McMurtry and Ossana from a short story by E. Annie Proulx (The Shipping News), the story centers on two men (Ledger and Gyllenhaal) who meet one summer as sheepherders in Wyoming and form a bond of love that spans 20 years. Hathaway plays the strong-willed ex-rodeo queen wife of Gyllenhaal's character, while Quaid will play the hard-bitten foreman who employs the two cowboys. Michelle Williams has already been cast as the wife of Ledger's character.
