Here's how the cast of 'I, Tonya' compares to the real-life people behind the drama

Margot Robbie plays Tonya Harding, the disadvantaged but persistent ice skater caught in the middle of the drama.

The movie gets the costumes right. Here's the real-life Harding right after she became the first American woman to perform a successful triple axel in a competition.

Sebastian Stan plays Jeff Gillooly, Harding's ex-husband who hired someone to break Nancy Kerrigan's leg.

Here's Gillooly entering the FBI headquarters in 1994. The movie got his moustache right.

Paul Walter Hauser has a breakout role as Shawn Eckhardt, Harding's bumbling bodyguard.

Eckhardt worked hard to distance himself from the attack after the scandal passed, changing his name to Brian Sean Griffith. Here he is in an interview with Diane Sawyer in 1994 on ABC.

Allison Janney plays LaVona Fay Golden, Harding's larger-than-life mother.

The real-life LaVona Fay Golden, who's estranged from her daughter, is just as idiosyncratic. Here she is in a recent interview with "Inside Edition."

Julianne Nicholson plays Diane Rawlinson, Harding's coach and possibly the only steady figure in her life.

The casting is spot-on. Here's the real life Rawlinson in 1994, speaking to reporters about the Kerrigan attack.

The movie doesn't actually show much of Nancy Kerrigan. Caitlin Carver's biggest scene in the role is when she was attacked.

Once again, the outfits are perfect. Here's Kerrigan in Lillehammer, Norway, during the 1994 Olympic games.
