Warner Bros.' upcoming Suicide Squad is by no means your traditional comic book adaptation. For one, the story centers on a group of villains, although there will be at least one superhero sighting we know of from Ben Affleck's Batman. We've also heard a number of bizarre stories from the set regarding the method acting ways of Jared Leto, who wouldn't break character during the production and sent a number of unusual gifts to his cast-mates. Today we have new details that shows just how unusual the production was, from director David Ayer.

The filmmaker brought together a star-studded cast for Suicide Squad, with Will Smith portraying Deadshot, Jared Leto as The Joker, Margot Robbie as Harley Quinn, Jai Courtney as Boomerang, Joel Kinnaman as Rick Flagg and Viola Davis as Amanda Waller. Yahoo! Movies got a chance to visit the Toronto set, where director David Ayer made an interesting revelation about the rehearsal process. Here's what he had to say, revealing that he actually made these A-list stars fight each other.

"The rehearsal was very intense. It wasn't a normal rehearsal, we'd talk about their lives, their history, and really got them to open up as people to each other. I also had them fight. I had them fight each other. You learn a lot about who a person really is when you punch them in the face. It gets rid of a lot of the actor stuff."

As unusual as this rehearsal process is, it seems to fit in quite nicely with the movie's aesthetic. Of course, it's unlikely that any cameras were rolling while these rehearsal fights were taking place, but they sure would be entertaining to watch, perhaps as bonus features on the Suicide Squad Blu-ray and DVD release. The director also revealed how much he adores Margot Robbie as Harley Quinn, teasing that this will be a breakout role for the actress.

"I don't know what to say other than a star is born. She's riveting, magnetic, she is the character. I don't recognize her out of make-up, we spend so much time together on set, I'm uncomfortable around her if she's not in make-up. Harley's one of my favorite characters. She's one of the reasons I wanted to do this project. She's so complex, she's all about dichotomies, so many opposing qualities in the same person, just like all of us. It's nice to explore those things. It's rare to have such a strong female character who's so active in the story, so driven and so powerful - yet has these weaknesses and achilles heels, just like anybody."

Margot Robbie also spoke about working with Jared Leto as The Joker. While we still don't know much about the plot, it's been clear from the set photos and videos that Harley Quinn and The Joker spend a lot of time together, which the actress revealed can be both interesting and terrifying. Here's what she had to say below.

"It's really interesting. Sometimes it can be awkward, sometimes it can be terrifying, most of the time it's just funny. I'm trying not to laugh, because he says such hilarious things. Jared's really funny, and terrifying, and just nuts. Absolutely nuts. It's really interesting to work with someone so method, because I haven't worked with someone doing that before."

This DC Comics adaptation follows a team of the world's most dangerous, incarcerated Supervillains, who are provided with the most powerful arsenal at the government's disposal, and sent off on a mission to defeat an enigmatic, insuperable entity. U.S. intelligence officer Amanda Waller has determined only a secretly convened group of disparate, despicable individuals with next to nothing to lose will do. However, once they realize they weren't picked to succeed but chosen for their patent culpability when they inevitably fail, will the Suicide Squad resolve to die trying, or decide it's every man for himself? Stay tuned for more on Suicide Squad as we get closer and closer to the August 5 release date.
