would've been a great James Bond...
If the character was suddenly changed to being Asian, of course. I'm not a fan of diversity for diversity's sake, and I'm certainly not seriously suggesting EON to consider picking this guy as their new Bond after Craig.
However, IF James Bond had to be turned into a Chinese guy for whatever reason (to allow the CCP to show the film in their country, most likely), Tony Leung would've definitely been the guy to get. All those quiet, contemplative looks he gave in films like In the Mood for Love, Lust, Caution, and Infernal Affairs felt very James Bond to me (as in, the Bond of the novels) and he could certainly pull off being an action star. Dude is suave and sexy as fuck too (no homo).
Who's with me?
