10. There is a Secret Cinema Hiding Behind This Tardis
Anyone who has seen the TV series Doctor Who is already familiar with The Tardis. Just in case you aren’t, this is a blue police box commonly seen in the UK, but it’s actually a gigantic time travel machine once you get inside. A company called Gramophone Home Theater is behind this creation. On the outside, it just looks like a life-sized Tardis owned by a Dr. Who fan. But once you open the door, you realize it’s a doorway to a secret cinema room.

Similar to the secret Batcave cinema mentioned earlier, this is a really fun way to reveal to your guests that you have an entire movie theater hiding somewhere in your house! And if you were feeling paranoid about burglars stealing your expensive equipment, this might also be a clever way to ramp up your home security system.
