Johnny Cash?s daughter is upset with a portrayal of her mother as a ?mad little psycho? in the new film Walk the Line.

Kathy Cash was so irked by the wrongful portrayal of Vivian Liberto Distin, Cash?s first wife, that she walked out of a special screening of the movie for her family.

?My mom was basically a nonentity in the entire film except for the mad little psycho who hated his career,? she says.

“She loved his career and was proud of him until he started taking drugs and stopped coming home.”

Kathy also objects to the fact that the film fails to show the singer?s children and their suffering during their father?s fight with drug addiction and their parents? divorce.

However, she praises the performances of Joaquin Phoenix as Cash and Reese Witherspoon as June Carter Cash, the singer?s second wife.

Distin and Cash were married for 13 years and had four children together.

Cash died in September 2003 at the age of 71.
