A group of kids in a coastal Oregon town follow a pirate treasure map to try to save their neighborhood from being torn down. Steven Spielberg came up with the story, and Chris Columbus wrote the script.
How it was made
The pirate cavern and ship were built on Stage 16 at The Burbank Studios (now Warner Bros. Studios Burbank).
Donner kept the actors from seeing the ship until they filmed the scene.
The museum where Mikey's father works is the Captain George Flavel House Museum.
