The veteran actor stars in the upcoming remake of the classic tale, about a young boy who lives in the woods with a mythical creature.
Redford, 79, plays a woodcarver who raised his children with stories about a dragon hiding in the forest, and it was this fantastical element that immediately appealed to the star, reported Contactmusic.
"I knew the fact that it was more diverse than anything I had done up to that point," Redford said explaining his own childhood saw him grow up in a working-class neighbourhood with little to do, making storytelling a form of escapism.
