Derren Brown's Secret Underground Lair

If I ever build a house, I hope to include a secret passageway of some sort. Derren Brown is way ahead of me, because his home includes a secret chamber. As reported at FHM.com:

“Over there, pull that lamp…” [Derren] points to a wall-mounted light beside a big bookshelf. We do as we’re told and the bookshelf swings open to reveal a secret staircase to an underground lair. “That’s my steam room,” he says at the bottom of the stairs before turning along a short corridor, “and this is my cinema. Nice, isn’t it?” Its red velvet carpet, six large seats and 10ft screen speak for themselves.

The rest of the article is worth reading, too, but of course nothing is more impressive than a secret underground lair.

There's another famous Brown with a secret passageway -- Da Vinci Code author Dan Brown has built some secrets into his house, too, as have a few other notable people: Secret Passageways.
