The embattled production has sparked legal proceedings over breaches to a co-financing deal with distributor New Line Cinemas and a stunt performer over an unscripted rape scene.

A stunt performer is suing Kevin Costner, saying she was compelled to perform in an unscripted rape scene in a film he was directing that broke Hollywood production rules and left her traumatized.

A stunt double said she was left with trauma by an unscripted scene that did not include an intimacy coordinator. Mr. Costner’s lawyer said the claims were meritless.
