Margot Robbie Films 'I, Tonya' with Her Co-Stars

Margot Robbie is hardly recognizable on the set of I, Tonya!

The 26-year-old actress is playing the title role of Tonya Harding in the film, and was seen on set with her co-stars on Sunday (January 22) in Atlanta, Ga.

Sebastian Stan and Allison Janney were also on set.

Allison stars as Tonya’s mom LaVona Fay Golden and Sebastian stars as Tonya’s ex-husband, Jeff Gillooly. In real life, Jeff hired a hitman to attack fellow ice skater Nancy Kerrigan so she wouldn’t be able to compete in the 1994 Winter Olympics. Nancy recovered in time and landed a silver medal in the games, but Tonya ended up getting banned from the sport for hindering the prosecution in the case.
