Odell: How much notice do you have to give? much does paxil cr cost without insurance Joaquin Phoenix pulled out all the stops to play Johnny Cash in the 2005 biopic 'Walk the Line.' He started by dropping his voice a couple octaves and learning the guitar, one-upping Jamie Foxx's lip-synching in the previous year's 'Ray.' Phoenix then tweaked his playing technique because it didn't match the Man in Black's style closely enough. Phoenix was nominated for the Best Actor Oscar in this role, but ultimately lost to another biopic actor, Philip Seymour Hoffman. However, Reese Witherspoon, who playedCash's wife, June Carter, took home Best Supporting Actress.
