Asians cannot judge western actors...
They immediately think, "A white western actor! will give us instant credibility!". Particularly if they are American and are well known as in this case. Not knowing that Nick Cage hasn't made a good movie in 20 years and they probably never saw the SW Prequels.
Europeans don't suffer from this but any film produced in China, Korea, etc you see this pattern.
Seriously, when is the last time you saw an epic film mixing cultures? They all suffer from cliches and end up being someone's fetish fantasy movie.
Stories are definitely lacking in the movie industry.
