Li Mu Bai? Why, he was a fighter, of course.
Li Mu Bai: male human; ftr17; CR 17; HD 17d10+85; 183 hp; Spd 30 ft; AC 29; Atk +29/+24/+19/+14 melee (Green Destiny, 1d6+11/12-20); SQ dimension door 1/day, air walk 2 hrs/day; AL LN; SV Fort +20, Ref +19, Will +16; Str 20, Dex 24, Con 20, Int 13, Wis 19, Cha 15.

* like winged boots, but substituting the air walk spell for fly.
** like the cape of the mountebank, but without the dramatic puff of smoke.
All that gear fits in under the equipment limit for a 17th level PC, using the DMG tables.
But he didn't _have_ that gear in the movie, I hear you say. Well, perhaps he did, and perhaps he didn't. There are ways of giving high-powered PCs magical abilities without straining credibility vis-a-vis magic items. See AEG's Magic of Rokugan for a great example of how to handwave away D&D-scale magic in an ostensibly low-item-count world.
IMO, this just goes to show how high-level D&D is 99% wuxia. Every high-level character worth his or her salt (at least any high-level character who wants to survive) is going to be able to fly and teleport. The only wart is the presence of heavy armour, but even that isn't always a given -- many groups seem to prefer light or no armour, seeing the disadvantages of full plate as outweighing the benefits.
