Witherspoon, Phoenix on Cash 'Line' LOS ANGELES (The Hollywood Reporter) --- Joaquin Phoenix (news) and Reese Witherspoon (news) are teaming up to "Walk the Line," the Johnny Cash (news) biopic to be directed by James Mangold, with Phoenix set to star as the country music legend and Witherspoon toplining as his wife and bandmate June Carter. The Fox 2000 project, for which deals are still being negotiated, is gearing up to start production in the fall with Mangold's wife, Columbia-based Cathy Konrad, producing along with James Keach. Co-written by Mangold and writing partner Gill Dennis, "Walk the Line" is described as a nontraditional biopic centering on a snapshot of Cash's life with a focus on his younger years shifting to Memphis when country started to heat up. ... ========= Joaquin as Cash? "nontraditional biopic"?? I am SO THERE! Reese as June? Bizarre-o-rama, but she can act, so it'll be interesting. James Mangold directed Identity (2003), Kate & Leopold (2001), Girl, Interrupted (1999), Cop Land (1997) and Heavy (1995). The only one of those I've seen is Cop Land, which I liked a lot. K&L? Well, everybody has to pay the rent. Gill Dennis hasn't written much, but he did write one of my all-time favorite films, Return To Oz, so we know he can write dark and nontraditional.
