Boomerang and Harley Quinn Have A Brother-Sister Type Relationship in Suicide Squad

“I think he’s an idiot” is the script note that Margot Robbie wrote for Harley Quinn when she first meets Captain Boomerang in Suicide Squad. “She has moments where she’s like ‘He’s funny,” and then goes back to, ‘He’s an idiot.’”

That’s one of the things the actress revealed to Comicbook.com and select other press during a set visit to Suicide Squad in Toronto last summer, as the cast, in the middle of filming a rainy outdoor night scene, bundled up and took some time to chat. It didn’t hurt that she was standing next to Boomerang’s portrayer Jai Courtney at the time. The playfulness came off instantly, as you could see how a little of Margot got into Harley and vice-versa, and how the relationships on screen leaked into real life, something every member of the cast and crew we spoke to during the visit mentioned.

“There’s this great kind of, I mean that’s what I think makes this movie so fun is there’s so much antagonism between them all, and we all have our, you know, sort of roles to play amongst the group,” Courtney said of their interplay. “I definitely pick up the kind of class clown slack at times. I mean Harley does a great line where she says, ‘I think a village in Australia is missing it’s idiot, you should call home.’ Which is a great line and does somewhat sum up things.”

Robbie chimed in, “I think they’ve got like a brother-sister relationship, and they just kind of niggle at each other a bit.”

“There’s kind of mutual respect amongst them all at a certain point, Courtney added,”and I mean that’s not something that necessarily is there from the beginning, but when they sort of come around to the idea that they need to band together and in a way are all they have, that’s sort of one of the beautiful payoffs of this ensemble.”

Suicide Squad, starring the pair of Australians and others, hits theaters August 5, 2016.
