Margot Robbie appears to have a motorcycle scene in Suicide Squad.

The 24-year-old Australian actress was spotted on a bike as she rehearsed this week in her regular clothes and a black helmet.

Robbie will portray Harley Quinn in the film, with Jared Leto as the Joker, Will Smith as Deadshot, Joel Kinnaman as Rick Flag, Jai Courtney as Captain Boomerang and Cara Delevingne as Enchantress.

The star was also seen with Leto's stunt double as they drove in the Joker's purple vehicle. A stunt double in a Batman costume was later spotted on top of the car, seeming to confirm Ben Affleck will appear as the superhero in the movie.

Suicide Squad is directed by David Ayer (Fury), and opens in theaters Aug. 5, 2016. The film follows the titular team of antiheroes as they perform dangerous missions for the U.S. government in exchange for commuted prison sentences.

Robbie is known for playing Donna Brown on Australian soap opera Neighbours and Laura Cameron on ABC series Pan Am. She starred in The Wolf of Wall Street with Leonardo DiCaprio, and is also scheduled for Tarzan with Alexander Skarsgard.
