In My Darling Vivian, director Matt Riddlehoover traces the romantic, wrenching, and dizzying journey of Vivian Liberto, Johnny Cash's first wife and the mother of his four daughters. Produced by Dustin Tittle, the grandson of Vivian Liberto and Johnny Cash, the film has exclusive, unprecedented access to never-before-seen footage and photographs, as well as to Vivian and Johnny's daughters themselves. Meet the first Mrs. Cash as her daughters, Rosanne Cash, Kathy Cash Tittle, Cindy Cash, and Tara Cash Schwoebel, share first hand, and for the first time, the entire story of love, isolation, fear, heartbreak, and survival.
