Gladiator of course, and "Kingdom of Heaven" although I'd have to stick to the extended version here. The cinema version is crap compared to this.
Edit: slightly out of timeframe, but "Alatriste" with a surprisingly not bad at all Viggo Mortensen was pretty good too. 16th century warfare with some action in the bogs of Flanders and an interesting depiction of a pitched battle of pike formations against each other in the end.
