The new movie I, Tonya recounts the bitter rivalry between Tonya Harding and Nancy Kerrigan, America's top competitors on the 1990s figure-skating scene. It also chronicles the shocking denouement of that rivalry, a moment New York Times reporter Jere Longman dubbed "the most horrifying, embarrassing and ultimately beneficial moment in the history of the sport." He was referring, of course, to the January 1994 day when a hitman, hired by Harding's ex-husband Jeff Gillooly, clubbed Kerrigan in the knee with a police baton during a final practice before the U.S. Women's Championships in Detroit.
