I, Tonya is a 2017 American biographical sports mockumentary comedy film directed by Craig Gillespie from a screenplay by Steven Rogers. It follows the life and career of American figure skater Tonya Harding and her connection to the 1994 assault on her rival Nancy Kerrigan. The film states it is based on "contradictory" and "totally true" interviews with Harding and her ex-husband Jeff Gillooly, suggesting they are unreliable narrators. This means the viewer must decide for themselves whether to see the film as the truth or as a version concocted by Harding herself. It features darkly comedic interviews with the characters in mockumentary style, set in the modern day, and breaks the fourth wall. Margot Robbie stars as Harding, Sebastian Stan as Gillooly, and Allison Janney as Harding's mother LaVona Golden. Julianne Nicholson, Caitlin Carver, Paul Walter Hauser, and Bobby Cannavale also star.
