Pete's Dragon (2016)

A young boy, Pete, is found in a forest where he's been living for six year after an accident took his parents' lives. A ranger, Grace, takes him in and asks him how he survived all by himself. He says he had a friend named Elliott and draws a picture of a dragon, saying it's Elliott. Grace takes the picture to her father who claims that years ago he encountered a dragon in the forest. Grace takes Pete back to the forest and he shows her his home and Elliott. A man sees Elliott, and when he tells about his experience and isn't believed, he sets out to capture the dragon to prove it.
