Top Ten Diva-licious Actresses In Musical Biopics (page 8)
3.[lastfm link_type="artist_info"] June Carter[/lastfm] (played by Reese Witherspoon)-Walk The Line
While Walk The Line was an expertly acted film about Johnny Cash (played by Joaquin Phoenix), Reese Witherspoon did a fabulous job playing his musically inclined wife, June Carter.
Witherspoon made us believe the chemistry between her and Phoenix as a he played the tortured, struggling musician and she played the effervescent, yet frustrated wife who also happened to be a musician.
