Trivia: When the Fratellis first catch up with the kids, Data yells out, "Holy S-H-I-T". On the DVD Commentary, Ke Quan explains he spelled out the word because his mother did not allow him to curse. He figured if he spelled it, that it didn't really count as cursing.

Trivia: When the Goonies descend into the fireplace, Ma Fratelli, Jake and Francis walk into the room. Ma Fratelli makes a comment about someone having been there, as the water jug is busted. Jake replies that maybe it was just a tremor. She responds by saying she'll show him a tremor and slaps him. As she does, she accidentally yanks Francis's headphones out of the jack and he almost drops the walkman he's holding. He starts to crack up with laughter, but manages to hold it together.
