There's a bunch of really good Chinese films that are set contemporary to the Classical era.
Hero,
Red Cliff and
The Lost Bladesman, off the top of my head. I don't know if that counts, but I'm sure the visual difference is as obvious to Chinese audiences as the difference between
Gladiator and
Robin Hoodis to us.
I have a soft-spot for
Troy, not so much because it's all that good, but I admire that they committed to the Mycenaean setting. They mostly avoided defaulting to "movie Greece" in the costuming, weapons and architecture, and the two exceptions- the armour of the Myrmidons and the boats- have at least been altered enough to show they were aware of the issue.
edit: Oh, and there's
a bunch more of varying quality. Lessee, er...
Sacrifice wasn't to my taste, I think you have to understand Chinese drama a bit better than I do...
Confucius was kinda dull, basically a hagiography...
Battle of Wits is good, Mohist themes are a unique touch, and Andy Lau is
sooo handsome...
Little Big Soldier was a lot of fun, manages to pull off both the historical setting and the Jackie slapstick...
Empress and the Warriors was okay, bit heavy on the wire-work,
White Vengeance is pretty good,
Three Kingdoms: Resurrection of the Dragon is visually very impressive, but pretty forgettable when stood against
Red Cliff, and
Mulan was honestly just boring. There's also
The Assassins, which isn't listed here for some reason, but is also pretty good.
edit2: Whoops, nuked my own post...
I liked
300. As an historical epic, it's trash, sure enough, but the trick is to watch it as an exercise in homoerotic fascist mythology. Snyder didn't realise he was making fascist cinema, so it doesn't commit as well as it might, but there's enough shouting and flexing and good ol' palingenetic ultranationalism to work.
