Chris Rock’s new documentary Good Hair is set for a limited release in theaters this Friday. But the celebrations will be bittersweet.

The comedian is now being sued for $5 million from a woman who claims he stole her idea to produce a documentary about the history of African American hair.

Regina Kimbell, who directed and produced the 2005 documentary My Nappy Roots: A Journey Through Black Hair-itage, is suing for the following: copyright infringement, unfair competition, fraud and deceit. She’s also seeking a trial.

In short, she alleges that there are over a dozen similarities between the two films. MSNBC reports the following:

She … claims both films are “socially and politically conscious”; both films were inspired by the filmmakers’ respective daughters; each film includes interviews with medical professionals — in the case of “Nappy Roots” a doctor was used while “Good Hair” used a dermatologist; both films interviewed hair care pioneers; each film looks at how India is involved in the use of weaves; both films have comedians to add “comic relief”; both have “celebrities tell their own hair stories”; both tour a “manufacturing plant where hair relaxers are maid [sic]” and more.

Rock’s people had no comment when asked, according to the report.

In other Rock movie news, he’s just signed on to star in Will You Be My Black Friend, an Oprah Winfrey-helmed project about the humorous attempts of a white man who tries to befriend black people. The film is based on a 2008 article printed in GQ, wherein the writer tries to find a black friend through a Craig’s List ad.
