Playing the redneck sheep rancher boss of Heath Ledger and Jake Gyllenhaal in the critical and box office hit Brokeback Mountain (2005), Randy filed a lawsuit against the film's distributor, Focus Films, and its producers seeking at least $10 million claiming he was fleeced into working cheaply by the filmmakers' assertion that the film was "a low-budget, art-house film, with no prospect of making any money." The movie won three Oscars, included best director for Ang Lee and topped $82 million at the domestic box office. He reportedly dropped the suit after his lawyers told him Focus agreed to pay him a bonus, which he claims would be split between him and other principal cast members. Focus denies any such settlement; however, the lawsuit has been dropped.
