Todd Stashwick, an actor with no writing credits to his name, is co-writing Suicide Squad 2 and if that's not a testament to DC's commitment to quality, I don't know what is. As an actor, Stashwick has appeared in Gotham, Teen Wolf, and 12 Monkeys.
Stashwick hit it off with director Gavin O'Connor on a movie they worked on together, leading to his working on the film. Other writers on Suicide Squad 2 include O'Connor and David Bar Katz.
Suicide Squad 2 will unfortunately come out someday.
