The best story I’ve heard about the production of Matilda was:
The scene where Matilda was dancing around her living room making things fly around to the song “Little Bitty Pretty One” was very nerve-wracking for Mara. She told Danny that she was anxious to do the scene, and he said, “You know why? Because you’re the only one dancing! We just have to have everyone else dance too! Then it won’t be scary!”
So everyone–the crew, the rest of the cast, the people at the craft services table, everyone–danced along with the song, at Danny’s insistence. Apparently the only one who wasn’t doing the full on dance was the camera man, who just did a foot shuffle so the camera wouldn’t jiggle.
If that’s not the sweetest thing ever I don’t know what is.
