TRAILER: Margot Robbie wows in Suicide Squad teaser

AUSTRALIAN Margot Robbie is wowing the internet after the latest trailer for Suicide Squad dropped this week.

Playing Harley Quinn -- the love interest of Batman nemesis The Joker -- her girly yet frightening character injects doses of humour in the much-hyped comic book film.

In one clip, she is seen astonishing military officers as she flaunts a pair of tiny blue-and-red pants and pull a tight-fitting shirt over her bra.

The film has had to return to shooting to add more humour to the film after the success of Marvel's darkly hilarious Deadpool.

Suicide Squad is expected to hit Australian cinemas on August 5.
