Yeah, still don't see it with O'Connell, at least looks-wise. Every other aspect he's lightyears ahead of most of these guys though.
About TheBatFan's stuff on Bale, totally agreed. Seems kinda funny looking back, he was only 30 when casting for Begins was going on. That's damn young, but Bale felt like a fully-rounded adult. Y'know? It's not like there's that much of a generation difference here, 15 years or whatever, but Bale at 30 seemed like an adult man who'd been around the block and seen some ****. So many of these people being discussed (not all, but a lot) aren't all that much younger than he was then, if at all, but it's like apples & oranges.
That being said, I'm all for going young this time around, if only to separate it from the Snyder stuff, do a hard break and make it clear to the general audience it's a whole different beast. But if you're casting 27/28 or whatever, you've gotta cast someone who you can buy into them having been travelling around the world, getting roughed up physically and earning some scars on their soul along the way. That's a "mature" 27/28, you can't just grab any prettyboy actor with a hit or two under their belts and a currently hot name in the industry.
O'Connell has that Bale thing in spades, puts him way ahead of these others. Find it a little hard to visualize him as Bruce looks-wise, but that's just pure cosmetic/surface-level stuff, that's not as important as the substance stuff.
