Dragon Heart (USA)

Dragonheart follows the story of medieval dragonslayer Sir Bowen in his attempt to rid the world of a particularly evil king along with seven evil dragons that have ruled the world (the seven evil dragons never appeared in the film). On the way, he befriends the last dragon to exist, Draco. Sir Bowen and Draco must join forces to defeat the king's army and rescue a damsel in distress. It drops out some of the film's plot, but it is still a close match.
