Margot Robbie Tells Us How She Got Cast As Harley Quinn In 'Suicide Squad'

It pays to have good chemistry.

Speculation about "Suicide Squad," the DC Comics-based supervillain movie slated for August 5, 2016 is running rampant, and the film's already-cast stars aren't doing a lot to clarify -- or discourage -- fan discussion.

Jared Leto, who will play the Joker, is out eating sandwiches to prep for some reason, and Will Smith is going around talking about making history as Deadshot.

Margot Robbie, currently making the rounds for her new film "Focus," in which she also stars alongside Smith, also kept pretty tight-lipped about her prep to play Harley Quinn while chatting with MTV News, but did let slip that the part came to her -- not vice versa.

"I actually got offered this one, I didn't audition, which is a real step up as an actor when you can get offered things," Robbie said.

The directors already knew that she and "Focus" co-star Smith would knock it out of the park together as Harley and Deadshot, so, "we didn't have to do chemistry reads or anything like that, and then I already knew, vaguely knew Jared Leto, who's playing the Joker."

She did, however, give hints about director David Ayer's tone for the film.

"I think on a scale of like, 'Dark Knight' is here and 'Avengers' is here, I think it's more on the 'Dark Knight' side of things," she said.

"Focus" hits theaters February 27.
