The shooting of new Harry Potter movie 'The Deathly Hallows' was stalled after two naked men were spotted running through a woodland scene.
Kids don't do this at home it is expensive for studios to have to re-shoot a scene. Besides the editor has a magic wand and with a wave of it and the magic phrase "Censio Stupido" he can fix any scene removing whatever he wants.
