A Suicide Squad source was recently quoted saying the following in regards to the potentail for Suicide Squad spin-off movies:
“They’re going to do a sequel for sure, and the recently announced Harley Quinn spinoff with Margot Robbie has got everyone excited, but their plans don’t end there. The studio is feeling very confident in the property. They think it’s going to be a really big hit and they think audiences are going to fall in love with these characters.
The Joker is a definite possibility for a spinoff, and Jared [Leto] seems up for it. I’ve heard more than a few talks of giving some of the other Task Force X members their own spinoffs. And like the Harley Quinn one, these films would open the door for a ton of new DC characters to show up. They’re also really hot on Jai Courtney’s character Boomerang right now. Nothing’s set in stone yet, but you’re definitely going to be seeing a lot more of these guys in the years to come.”
