Walk The Line‘s insightful, candid portrayal of Johnny Cash is based on two autobiographies authored by the country singer-songwriter: 1975’s Man in Black: His Own Story in His Own Words and 1997’s Cash: The Autobiography. Joaquin Phoenix and Reese Witherspoon excel as Cash and June Carter with ample time given to their enduring chemistry, as well as the demons that blighted the former’s career. Ultimately, this is a tale of music, redemption and a love that conquered all.
