The movie will follow Harding as she trains for the 1994 winter Olympics before the infamous attack on rival skater Nancy Kerrigan.
Kerrigan was attacked by a hitman hired by Harding’s ex-husband Jeff Gillooly after a training session, but he failed to break her leg and she went on to win silver in the Olympics while Harding placed 8th.
Gilloy took a plea bargain against Harding and was released from prison after just one year. Harding pleaded guilty to hindering the prosecution and received three years probation, 500 hours community service, a $US160,000 fine and a lifetime ban from the sport.
I, Tonya is scheduled to hit cinemas in 2018 and also stars Sebastian Stan and Allison Janney – the role of Nancy Kerrigan is yet to be confirmed.
