I like his look. Can't really speak on his acting though, since I don't remember him from Westworld. I will say that I do think for this incarnation there may be a slight chance a PoC actor gets cast, since it'd be an immediate way to set themselves aside from Pattinson. Haven't seen many PoC suggestions though, and I can't really think of many off the top of my head.
Speaking of Westworld, I saw some Brandon Sklennar of 1923 suggested on Twitter. I didn't really pay much attention to it since I saw some pics of him clean shaven in red carpets and thought he looked a bit ridiculous, but then I saw his small appearance on Westworld and I can kinda see it now:

He's 30 but looks like he could play older and more mature (in fact you could've told me he was 40 based on these images and I'd have believed it lol) he seems to have a decent enough voice, he's 6'2. Only thing is that I feel he'd have to bulk up a lot to be fully convincing as this type of Batman, but I guess it's not unreasonable to expect that DCU actors will probably go through the same MCU type of transformations.
Not really into it, feels like a better Hal Jordan or something, but it's an option if they really wanna go younger I guess. Wouldn't surprise me to see him in contention for Superman either actually, though he doesn't feel quite right for that either. Something about his eyes.
