From director John Woo.
The film is about the Battle of the Red Cliff, around 208 AD between the Three Kingdoms. Battles on both land and (wide) rivers.

There are Kongming Lanterns (early hot air ballons) shown in the movie trailer. Albeit they weren't for manned flight, but for lighting up the battlefield sky at night.
