“Suicide Squad” star Margot Robbie, who is playing Harley Quinn, was afraid that Jared Leto, The Joker, would beat her up on set. Leto took his method acting too far to the point of “bizarre,” and that worried Robbie.

“When I first heard that he was method (acting), and that we couldn’t refer to him as Jared and things like that, I started to panic a bit because I’m in an abusive relationship with this guy who thinks he is the character. I was worried I’d get beat up on set,” Robbie told Slash Film in an interview.

Method acting as a troubled-yet-lovely Rayon in “Dallas Buyers Club” was one thing. However, method acting while playing an abusive, psychotic super-villain is something completely different. In 2015, some behind-the-scenes photos showed The Joker kissing Harley and then hitting her with full force.

“You don’t know what the Joker is going to do next; you never do. It was intoxicating to have no rules,” Leto told Entertainment Weekly.

It was also revealed that The Joker would be obsessed with winning her lover back and that required Leto play a psychotic kind of love. No wonder Margot was afraid. However, the Australian beauty said that Leto was completely in control at all times and between takes would even ask if she was alright.

“He’s kind of terrifying. He’s really lovely, though. He’s very conscientious on set. He’s not completely lost in the character that he’s violent or anything. Between every take he asks if I’m okay ... he’s respectful, professional, and lovely. It is so incredible to watch him work because it is a really bizarre process and kind of fascinating. It’s not a process that would work for me but I can see the way he does it and it clearly works for him. It’s cool,” Margot added.
