Houdini used a trunk with a trap door in his Metamorphosis illusion. Some magicians, like David Copperfield, are outraged that this piece of information is publically available. As though we were all idiots and couldn't figure this one out. I see their point to an extent, but David Copperfield is a braying jackass, so whenever he makes a point, I'm less inclined to agree. Apparently saying you're not using camera tricks and then using camera tricks isn't against the code of ethics, David? "My God, the Statue of Liberty, it's gone! That's right, here in this helicopter, I do not see the Statue of Liberty anywhere!" What a putz.
