Ahead of the trailer debut on Sunday, Disney has unveiled a motion poster for the remake of its 1977 classic "Pete's Dragon."

Directed and co-written by David Lowery (“Ain’t Them Bodies Saints”), the film is the story of an orphaned boy named Pete and his best friend Elliott, who just happens to be a dragon.

For years, old wood carver Mr. Meacham (Robert Redford) has delighted local children with his tales of the fierce dragon that resides deep in the woods of the Pacific Northwest. To his daughter, Grace (Bryce Dallas Howard), who works as a forest ranger, those stories are little more than tall tales … until she meets Pete (Oakes Fegley), a mysterious 10-year-old with no family and no home who claims to live in the woods with a giant, green dragon named Elliott. And from Pete’s descriptions, Elliott seems remarkably similar to the dragon from Mr. Meacham’s stories. With the help of Natalie (Oona Laurence), an 11-year-old girl whose father Jack (Wes Bentley) owns the local lumber mill, Grace sets out to determine where Pete came from, where he belongs, and the truth about this dragon.

Also starring Karl Urban, "Pete's Dragon" opens Aug. 12.
