Margot Robbie transforms into famous skater in 'I, Tonya' teaser

Australian actress Margot Robbie looks like she never has before in a new teaser clip for her upcoming film, I, Tonya.

The 27-year-old Wolf Of Wall Street star portrays Olympic figure skater Tonya Harding in the biopic, and sports a teal coloured leotard and tights as she glides across the ice in the new trailer.

Directed by Craig Gillespie, the film follows the real-life rivalry between Tonya and fellow US skater, Nancy Kerrigan.

The memorable incident in 1994 when Tonya's ex-husband tries to sabotage Nancy's chances at the Winter Olympics is also explored on screen.

• The tough role that made Margot Robbie cry

In a recent interview, Margot revealed she wasn't familiar with the back-story before signing up to do the film.

"To be honest, when I read the script, I didn’t know who Tonya Harding was, and I didn’t realise it was a true story," she told Vanity Fair.

But proving to be very dedicated to her role, Margot committed to four months of training with a professional choreographer, and even suffered a herniated disk in her neck.

Also starring the likes of Sebastian Stan and Allison Janney, I Tonya will release in the US in December before the awards season.
