Filmmaker sues Chris Rock over 'Good Hair'

LOS ANGELES (AP) -- A filmmaker is suing Chris Rock for at least $5 million and trying to block the release of his upcoming documentary "Good Hair."

Regina Kimbell sued Rock and several film companies in federal court in Los Angeles on Monday, claiming Rock's project is a copycat of her film, "My Nappy Roots."

Kimbell states she screened her film for the comedian in 2007. The lawsuit states "My Nappy Roots" traces the business and cultural history of black hair care and has otherwise only been shown at colleges and film festivals since its completion in 2006.

Her lawsuit claims several of elements of her film have been copied.

Rock's publicist declined to comment.

"Good Hair" will be released in certain cities on Friday and nationwide on Oct. 23.
