Brokeback Mountain: According to The Hollywood Reporter, Michelle Williams is being lassoed to star in Ang Lee's cowboy love story Brokeback Mountain for Focus Features.

Heath Ledger and Jake Gyllenhaal are starring.

Adapted by McMurtry and Ossana from a short story by The Shipping News scribe E. Annie Proulx, the story centers on two men (Ledger and Gyllenhaal) who meet one summer as sheepherders in Wyoming and form a bond and love that spans 20 years. The film tracks that time period and their evolving relationship.

Williams would play Ledger's wife, Alma, who has to deal with her husband's secret love.

"Brokeback" is slated to shoot in May.
