After making what he calls a "naive young actor" move on the set of "Notting Hill" during that famous brownie scene, Hugh Bonneville learned to never eat on camera. (This is just one of the many behind-the-scenes stories Hugh tells in his new memoir, Playing Under the Piano.)
"If you eat two on the wide shot, you have to eat two on the medium shot, you have to eat two on the close-up..." Hugh explains. LOL, whoops!
