In preparation for her performance in I, Tonya as Tonya Harding, Margot Robbie, best known until now for The Wolf of Wall Street, trained hard for four months to skate convincingly before the camera.

This and other issues about the making and meaning of I, Tonya are covered in this interview with director/producer Craig Gillespie.
