Dudes & Dragons (2015) on Netflix

Plot summary

When Princess Ennogard turns down the wizard Lord Tensley, he locks her away and unleashes a dragon he controls, vowing that until she accepts him it will destroy anyone in the kingdom who shows love. She gets word out by an enchanted dragonfly, asking for a true Dragon Warrior to free her. Elsewhere, the young warrior Camilan wants to marry the elf princess Larec, but his parents will not bless a match outside their race, since it would cost the family its birthright. His hope rests on his estranged older brother Ramicus, a bounty hunter who has no wish to settle down. The dragonfly reaches their camp with Ennogard's plea, and the promise of reward turns Ramicus toward the rescue.
