It was reported Allocine the he will indeed be in the film, though he isn’t about to say which character just yet.
“All I can say is that I’m going to be in the movie, and it’s going to be amazing,” Kinnaman said. In a separate interview he confirms he’s playing Flagg. The following comes from Uproxx:
You mention being aware of what the fans want, how does that play into what you want to do with Rick Flag in Suicide Squad? He’s not a super known character, so maybe you don’t have to worry about that as much and you can really own it.
Yeah, for sure. And you want the backstory of the character, but I think this is also a universe that David Ayer is going to create – there’s a lot more. Also, when you’re doing the first movie in a comic book, you always have the leeway of you’re going to move it from a comic book to a film and put it in real life – you’re always going to make a lot of changes and create a new universe. So you’re kind of setting a precedent. When you’re remaking a movie that’s already been made and a character that was made for the film, then it becomes a different thing and it’s more difficult to create something new without offending some people.
Were you familiar with the character of Rick Flag before this came up?
I know hardcore comic book fans who don’t know him that well.
I reached out to my guys, like Daniel Espinosa, who did Child 44 and Safe House and Easy Money. He’s a comic book authority; he’s read every Marvel comic since 1982. When he’s with Marvel people, he’s like, “No, that character had his golden age between 1984 and 1986 when so and so wrote that arc.” And even he wasn’t completely sure.
Kinnaman joins a cast that includes Will Smith playing Deadshot, Jared Leto as the Joker, Margot Robbie as Harley Quinn, Jai Courtney as Captain Boomerang, Cara Delevingne as the Enchantress and Viola Davis as Amanda Waller.
The film centers on the titular antihero team of incarcerated supervillains who act as deniable assets for the United States government, undertaking high-risk black ops missions in exchange for commuted prison sentences. The pic is set for an August 5, 2016 release.
Kinnaman will be seen in Run All Night as Liam Neeson‘s son this weekend and, ironically enough, he co-stars in Tom Hardy‘s next movie, Child 44 in April.
