Right down to her bedazzled costume and ‘90s permed hair, Margot Robbie is a dead-ringer for infamous figure skater Tonya Harding in the first trailer for dark comedy biopic I, Tonya.

“Once I put on the wig, which altered my hairline, and bleached my eyebrows, I started to see Tonya,” Robbie said told W magazine in October of her transformation.

“The hardest part was losing my natural laugh. It needed to be Tonya’s laugh.

“I couldn’t do a triple axel like Tonya, but I was able to master her laugh.”

If the first teaser is anything to go by, the Australian star mastered more than that, and she’s already drawing Oscar buzz since I, Tonya’s September premiere at the Toronto International Film Festival.

Her attention to detail included time on the ice. She’d never figure skated before, but “did four months of training, five days a week, four hours a day,” she told W.

“On Christmas Eve, I was at the rink. And now I actually really miss it. I kept my ice skates—but I said goodbye to a whole world of pain that I didn’t realize came along with figure skating.”

In the beginning of the trailer, she’s seen at the ice rink, leaning against a wall. She drops a cigarette she’s smoking and grinds it out with her skate blade.

“America, they want someone to love. But they want someone to hate,” Robbie says, nailing Harding’s Oregon accent.

“And the haters always say, ‘Tonya, tell the truth!’ There’s no such thing as truth. I mean, it’s bulls***.”

As the two-time Olympian, Robbie zips around the rink setting up for her triple axel – Harding was the first American woman to pull it off in competition – in a high-necked purple dress with ribbons of sequins.

The real-life Harding sewed her own costumes and they were reproduced for the film.

Directed by Craig Gillespie, I Tonya tells Harding’s story from her early skating to her training for the 1994 Winter Olympics, when her ex-husband Jeff Gillooly and her bodyguard hired a hitman to sabotage rival skater Nancy Kerrigan.

Despite disputing her involvement in the Kerrigan attack, she was eventually convicted of hindering the investigation in the incident.

Now 46, Harding was sentenced to three years probation, 500 hours of community service, and a $US160,000 fine.

She was also thrown out of competitive figure skating for life.

I, Tonya  is scheduled for Australian release on February 15.
