Creature Commandos are from Weird Tales Comics back in the 90's. They're the "Elites" and serve like a contingency group whenever Suicide Squad or any other Task Force group dies or defuncts. They're only known to the Government as well. Not like Suicide Squad which is public.
Yeah this is set in the new DCU which will have both animation and live action projects. This will however follow the events from The suicide Squad (2021) and Peacemaker season 1 so is kind of a bridge from the old universe (James Gunns projects specifically) to this new one, hence why some actors like Viola are returning
1:00 All facts, Keaton and Bale were just Keaton and Bale wearing Batman suits lol, of course that doesn't take anything from their great acting but they just wasn't the part. And regarding your wish that Batman is a older griddier veteran, i think that's the route they're taking. There are also mad rumours of him being Bronze Age 70-80's Batman who rocks the Blue and Grey suit with the white eyes and casually fights Metahumans, Freaks and other Superpowered beings even Supernatural at times. They will make the new Batman as opposite to Battinson as possible, older, morr experienced, has a son Damian Wayne, NOT grounded at all. Just so it would match the new fantastical universe.
Frank Grillo’s character Gen. Flag will appear in Superman and Peacemaker Season 2. Steve Agee’s John Economos and Viola Davis’s Amanda Waller will appear in Peacemaker Season 2 and the tv series Waller. None of the other characters are confirmed for projects yet, but… Circe will probably appear in Paradise Lost (tv series chronicling Amazon society prior to Wonder Woman’s “birth”). There are 3 Batman villains in this trailer (Dr Phosphorus, Rupert Thorne & Clayface) any of whom may possibly appear in Brave And The Bold (Batman movie title). IF Eric Frankenstein and Bride show up in live action it will more than likely be in Swamp Thing (movie in development).
