A brief skim over Johnny Cash's childhood in rural Arkansas and then we leap into his early career, powering along through the highs and lows until we reach 1968, a good time for the legendary balladeer and a perfect place to end a biog on a high note. Walk The Line is a film made by the two central performances of Joaquin Phoenix and Reese Witherspoon. The live scenes are hypnotic and the chemistry between the two never less than utterly convincing. Like 'Ray' this is a film that smoothes over much of the fact but triumphs through the sheer passion of the performance.
