During his talk with Collider, producer Charles Roven discussed Suicide Squad and the stories about actor Jared Leto's method approach to the Joker. "It was different, it was fun. The group first wasn't sure because the [assistant directors] had to call him 'Mr. J' to get him to come to the set," he said. The actor also isolated himself from the rest of the cast, but Roven saw there was, ultimately, a good purpose to the actor's choices.
"That's really what his character was, the purpose of his character in many ways, other than when he was with Harley or trying to get Harley. It was very entertaining, it was fuel for a lot of good sport and a lot of laughs, and his isolation bonded the squad, and we wanted the squad bonded," he said.
Roven also mentioned the film started as a pitch from writer/director David Ayer and that it was "essentially greenlit in the pitch meeting." He added that Ayer's keen interest in the concept made it an easier sell to the actors. "As he says 'it can be fun to be bad' and 'just because they're bad doesn't mean they're evil'," Roven explained. "And so he was able to convince all of the actors that we went out to that he was gonna be able to make these characters so compelling that they would wanna be played more than once by these actors."
The characters and their relationships are part of the reason Roven believes the film will be compelling to audiences.
Currently, the plan is for the film to receive a PG-13, but as the producer explained, it could end up "right there on the edge of PG-13, but still PG-13."
Suicide Squad opens on August 5th, 2016.
