Yes, that would be the perfect way to do Batman's combat style. The greatest AC player. Seriously, if they can get that style live-action, then we're in for a treat.
I think Keaton's Batman could whup Bale. Keaton's Batman makes it look so easy.
Something I hope to never see on the new Batman is that open mouth s**t. Bale's Batman always had his mouth open with his tongue showing as he talked. Pissed me off, especially in TDKR, when he was supposed to be all smooth in front of Selina. I have no idea how she found him attractive.
On a side note, this vid is pretty funny.
