Tom Cruise is planning to build a bunker at his Colorado home to protect his family in the event of an intergalactic alien attack.
Tom is reportedly fearful that deposed galactic ruler 'Xenu' is plotting an evil revenge attack on Earth.
According to American magazine Star, a source said: "Tom is planning to build a US$10 million bunker under his Telluride estate." The home can be seen below.
"It's a self-contained underground shelter with a high tech air purifying shelter."
The facility is said to have enough room for ten people - including wife Katie Holmes, 17-month-old daughter Suri and his adopted children Isabella, 14, and Connor, 12.
