"As far as I know they're writing the script, and I think the plan is to shoot it sometime in 2018, but that could change. I think I'll definitely come back for it," Kinnaman said.
The 37-year-old actor wants director David Ayer to return, but it seems unlikely, as Ayer is currently committed to direct "Suicide Squad" spin-off "Gotham City Sirens", according to The Hollywood Reporter
"Ultimately, I'd love for David Ayer to direct it, but if he doesn't want to direct it then someone who is great with character and that's able to ground the story and maybe put these characters in a more normal situation. It would be really interesting to see these crazy characters interact with regular people as well," he said.
