The Goonies

The cast was not allowed to see the pirate ship before the scene was shot. When they did see it, some of the kids said "holy shit!" so the scene had to be re-shot without them cursing.

Producer Steven Spielberg directed at least one scene in this movie.

Jeff Cohen got the chicken pox after he got the role of Chunk. He showed up to the set anyway, afraid that they would have replaced him otherwise.

The music played when the kids discover the tunnel in the Fratellis' hideout by accidentally pouring water down it, is the same piece of music played in The Great Escape (1963) when the Germans discover the prisoners' first tunnel by accidentally pouring coffee down it.
