Fan Casting How to train your Dragon (2010; Live Action)

The Viking village of Berk is frequently attacked by dragons that steal livestock and endanger the villagers. Hiccup, the 15-year-old son of the village chieftain, Stoick the Vast, is deemed too weak to fight. Instead, he creates mechanical devices under apprenticeship with Gobber, the village blacksmith. Hiccup uses a bolas launcher to shoot down a Night Fury, a rare dragon, during a dragon raid, but nobody believes him. He goes into the forest and finds the creature but cannot bring himself to kill him and sets him free instead; much to Hiccup's surprise, he spares him.
