After a breakout role in "The Black Phone," rising star Mason Thames pulls from his childhood fandom for new movie "How to Train Your Dragon."

How to Train Your Dragon follows Hiccup, the son of Butler’s Stoick, who has grown up in a society that hunts and kills dragons. But when he happens upon Toothless, an injured Night Fury dragon, he nurses the creature back to health, forming a close friendship with him that ends up changing his village forever.

Mason Thames may be leading the new How to Train Your Dragon movie — but he’s been a fan since day one. “That was my childhood, growing up with those movies,” the 17-year-old actor tells People, reflecting on what it means to now play Hiccup in the live-action remake of the beloved animated franchise.
