It wasn’t over creative differences, and it wasn’t because he’d lost faith in the project, and it wasn’t because Will Smith’s children made him feel uncomfortable (although, those would be fun rumors to start). The reason Tom Hardy — originally cast as Rick Flag in Suicide Squad — was forced to leave the project had only to do with a scheduling conflict, according to an interview Hardy did with Collider:
“There’s a very practical element as to why I’ve missed out on that foray, which is because Alejandro [G. Inarritu] has overshot by three months in Calgary, so we’ve got to go back out to Patagonia or Alaska to continue shooting The Revenant which has turned into a much bigger beast than we thought, but that also looks exceptional.”
The Revenant, by the way, stars Leonardo DiCaprio, Domhnall Gleeson and Hardy and it’s about Hugh Glass (DiCaprio), a man who — in 1820 — who sets out to get revenge on the men who left him for dead after a bear mauling.
Also, because that’s not a particularly exciting news bit, we should also add that Hardy was a huge fan of the screenplay for Suicide Squad.
“Warner Bros. is my home studio and I love them so I was really bummed out. I wanted to work on that and I know the script is really [frick]ing alley and I also know what’s gonna happen with The Joker and Harley Quinn in that; I won’t give away too much…it’s [frick]ing alley. And that whole territory is something that I would certainly—I mean, everybody loves The Joker. Everybody loves The Joker. Will Smith is a dope guy, but everybody loves The Joker and that’s gonna, I think, be a very important film for fans.”
“Alley,” by the way, is how they say “streets ahead” in London. Hardy picked it up from watching Community, which has specially written phrases for English audiences.*
Joel Kinnamon, replaced Hardy in Suicide Squad (the two worked together on the terrible Child 44).
