Gem might not be the best term, but list some titles you happened to watch that you found surprisingly good considering you'd never heard of it. Ironclad http://www.imdb.com/title/tt1233301/ Not heavy on dialog. Actually, not much dialog at all. But Paul Giamatti is the evil King, and basically it is the story of the Alamo or 300 in 12th century England. 20 Warriors hold off an army of thousands in a vivid bloodbath to enforce the Magna Carta on the king. Maybe not historically accurate, but a fun ride.
