In 1994, crime and ice skating collided when Nancy Kerrigan was clubbed in the knee at the U.S. Figure Skating Championships. Kerrigan's rival Tonya Harding was thought to be involved and eventually pleaded guilty to obstruction. Now, over 20 years later, we finally have a movie about it. Starring Margot Robbie, the black comedy comes to theaters December 8, 2017.
