My "wants" for a Batman reboot:
A suit similar to the new Cavill Superman suit... Flexible, intersting looking, have the traditional blue and grey but subdued, muted color like the Superman suit. This will allow for my next want:
Martial arts. I want Hong Kong film level martial arts from my Batman. Batman should be able to take five guys armed with guns out in seconds, totally negating the need for armor. Batman doesn't need armor because he's a badass. Period. Have someone like Donnie Yen be the fight co-ordinator.
Storywise, if it's a reboot and they absolutely HAVE to mention the origin, then have it be through someone doing research... Like say start the story off with Gordon arriving in Gotham ala Year One. He could learn about Bruce Wayne and Batman through stories form others, he could be the audiences "surrogate".
Now, who would I pick for Batman? Interstingly, he has already shown up in the Batman universe...
Desmond Harrington
He's young(ish), he can be intense, he's got the pretty boy looks for Wayne, and I dig his voice.
