Kevin Costner has filed to dismiss the sexual harassment lawsuit brought against him by a stuntwoman who worked on the Horizon sequel. After stunt performer Devyn LaBella claimed that she was forced to participate in an "unscripted, unscheduled rape scene" directed by Costner, 70, for Horizon: An American Saga - Chapter 2, the actor argued in a new filing that LaBella, 34, indicated via text that she had a great time filming the movie, according to court docs obtained by TMZ on Tuesday, August 19.
