He was so well into his character that his co-star, Will Smith did not even get the chance to exhange pleasantries with him while doing the film. They never got to talk apart from their lines in the script.

But it is not only Smith who had high regards for the dedication Leto has given his role, playing as the Joker of the movie, even Margot Robbie who plays Harley Quinn in the story, told the New York Daily News back in August how Leto was "locked into" in role.There was a time when she got really intimated with him, especially when he didn't have his make-up on.

She said,"I saw him out of makeup once and I was actually petrified of him. I was too scared to go up and didn't know who that person was, and when he got back into his makeup I was far more comfortable."

Adam Beach who is also an actor in the movie dished to E! News how he felt about Leto's method acting skill and talent. "He encompasses this beautiful man and he shows it in, 'Hello, how are you?,' but in an instant, he goes to psychotic behavior where you're in fear," Beach told the publication. He continued saying, "But you love him because he has both of those genuine sides."
