Trivia for Walk the Line (2005)
Joaquin Phoenix performed all of the songs himself without being dubbed and learned to play guitar from scratch.
Reese Witherspoon sang all of Carter's vocals for the film herself.
June Carter died before production began on the film, so Reese Witherspoon's research included looking through Carter's closet for inspiration.
Johnny Cash chose Joaquin Phoenix to play him in the film. June Carter reportedly chose Reese Witherspoon for her role in the film also.
Sony, Universal, Focus Features, Paramount, and Warner Bros. all passed on the project.
Reese Witherspoon did her own singing. She also had to learn to play the auto-harp.
