Dakota Johnson is set to star in upcoming court drama "Unfit". The "Fifty Shades Darker" actress will also serve as an executive producer for the fact-based courtroom flick which is set in 1920s under her Silhouette Productions.

Brett Ratner and John Cheng of RatPac Entertainment, meanwhile are producing. Based on Adam Cohen's book "Imbeciles: The Supreme Court, American Eugenics, and the Sterilization of Carrie Buck", the script was written by former litigation lawyer Melissa London Hilfers.

"Unfit" is the true story of Carrie Buck (Dakota), a young Virginia woman who became a lightning rod for that movement, whose 1927 Supreme Court case Buck v. Bell legalized the sterilization of "undesirable" citizens. Buck was forced to fight against it singlehandedly for the one thing she desperately wanted: to be a mother.

Dakota says, "Like many, I was not privy to this shocking and fascinating moment in American history. I quickly became obsessed with the prospect of shedding light on the massive misstep in American justice. Carrie Buck's story is poignant and galvanizing, and certain aspects are unnervingly congruent with the relationship between the government and women today. It is an important story that alongside RatPac and Amazon, I am honored and eager to tell."

Brett adds, "Dakota had told me about the book Imbeciles at a lunch last year, and when John Cheng and I read the spec script, we sent it to her immediately. I couldn't be more thrilled be involved in this project with Dakota and Amazon, because I know Amazon's passion and enthusiasm for telling this story is just as strong as Dakota's. Although this story took place almost a hundred years ago, the subject matter is unbelievably timely."
