Option 2:
Dragonheart
It's decades on from when Bowen, in his last year of life, is given the last dragon egg in existence and he places it in a monastery for safe-keeping. Protected and cared for by the monks, the dragon is nurtured in secrecy - which is all to the good because a prophecy comes that a dragon's heart will cause the land to become ruled by evil. The new main character, apart from Drake the dragon, is Geoff (sounding more like Joff, played by Chris Masterson) who is a stablehand, but is training with a home-built fighting machine to become a knight. There's fat chance of that, however, as the addled king has appointed Lord Osric (Harry van Gorkum) as chancellor and the beastly chap is out to make it impossible for those of Geoff's class to become anything other than peasants.
