DERMA, Miss. (WTVA) -- Christie Campbell-Smith and her husband Glen say they were in Arkansas recently at a family gathering when they were filmed along with the rest of the family.
Campbell-Smith says she is the niece of country music legend Glen Campbell.
They say the film is about the singer and his bout with Alzheimer's disease.
"I think they are doing him and Alzheimer's a real justice. They came, they followed him around on tour during his performances and they also came to Billstown, Arkansas, where we are from and filmed the whole family together as one and as a group supporting each other," said Campbell-Smith.
Campbell-Smith says she does not know yet what the film will be called or have a release date.
She says her uncle is holding up well.
