The Spielberg-produced 1985 film that follows Mikey Walsh and friends on a treasure hunt is The Goonies.
Directed by Richard Donner and written by Chris Columbus from a story by Steven Spielberg, the film follows children from Astoria, Oregon’s “Goon Docks.” Mikey and his friends discover a map leading to the lost fortune of the legendary pirate One-Eyed Willy.
The treasure hunt begins as the children try to save their homes from foreclosure. Their search takes them through tunnels filled with traps while the criminal Fratelli family pursues the same treasure. Sean Astin played Mikey, with Josh Brolin, Corey Feldman, Jeff Cohen, Martha Plimpton, Kerri Green, and Ke Huy Quan among the young cast.
A common mix-up is crediting Spielberg as the director. Donner directed the movie, while Spielberg supplied the story and produced it through Amblin Entertainment. The film was released on June 7, 1985, and entered the National Film Registry in 2017 for its cultural, historical, or aesthetic significance.
