London, July 14: Actress Margot Robbie has revealed she had to apply tactics of a psychologist to know her “Suicide Squad” co-star Jared Leto better as he was always in character and it was a task to know his real side. The 26-year-old star said she found it hard to “get through to him at first,” reported Female First.

“He’s in character all the time. I spent a lot of time trying to figure out their relationship. Because he’s got this facade up, it was really hard for me to get through to him at first. So I was like, okay, I gotta approach this as if I’m trying to crack the Joker,” Robbie said. (Also Read: Jennifer Aniston blasts tabloids over body shaming)

“It’s a test that psychologists use to determine what mental illness people might have. It’s a list of 500 questions or something. Whenever we had time to rehearse or improvise, or even in scenes, I’d just start with those questions … I’d see which ones would catch him off guard and how, how he’d react, and I’d be like, ‘Okay, I’m gonna go for this tactic now.'”
