Also I mentioned it before but I really can't help but have the sense that with the suit on he'd almost seem like a discount Pattinson lol. They have the exact same heights, exact same builds, are the exact same ages, and while it'd be hard to mistake one for the other unmasked, they both have these really angular, model-like jaws that look /great/ for Batman and are very Neal Adam-esque but would also make him look ridiculously similar to Robert when underneath the cowl.
That's the least of my issues with him though and I could easily overlook it if I saw him have more range or intensity or gravitas as an actor, but compounded it makes me not really be enthusiastic about him for this specific Batman. Which is a shame because there are probably other scenarios where I'd have liked to see him as Batman.
