Jared Leto Says He Still Has Some of the Joker Left in Him 'Somewhere'

Leto portrays the iconic character in "Suicide Squad."

Leto said he felt a “responsibility” in taking over the role. He described himself as becoming a detective and a journalist in trying to figure out how to embody the Joker.

“You start to investigate and ask questions and sometimes you don't find any answers. You fail a lot. You stumble around in the dark,” he said. “But you start to put together the pieces and get a sense of who this character is and, I have to say, it was the role of a lifetime.”

“It was the most fun I think I've ever had, playing a part,” he said.

“A lot of experimentation,” he said of his process. “I remember wandering the streets of New York and in Toronto where we were shooting, and I would just laugh out loud and see how people would react to it.”

“Every time when I started to hone in on this laugh, I realized it was the one that really, people would turn around and be like, ‘What the hell is that?’” he recalled.

Leto called his take on the Joker “sick” and “twisted” but also “very lovable” and perhaps ripe for a sequel.

“I feel like this film is an introduction to the Joker and I'm hopeful that we will see more to come,” he said.

“Suicide Squad” opens in theaters nationwide Aug. 5.
