John Carter Cash will have an acting role in Walk the Line, a film biography focusing on the early careers of his parents, Johnny and June Carter Cash. The film stars Joaquin Phoenix and Reese Witherspoon. In one scene, John Carter Cash will portray Bob Neal, a disc jockey at WMPS in Memphis, who first provided radio airplay for Johnny Cash's debut recordings, "Hey Porter" and "Cry, Cry, Cry." Noting that he has already visited the film set, Cash told CMT News, "It's going great. I really feel comfortable with it. It's a movie. It's not a documentary, but I truly believe that Joaquin is doing an excellent job. He sounds great. He's not doing a caricature of Johnny Cash. He is acting and doing a wonderful performance, very believable as my father. Reese is adorable. She's great. I got to spend some time with her, and she's just a wonderful angel. I believe that she's doing an excellent job as my mother."
