Tom Cruise and Katie Holmes are planning to build a £5 million bunker under their Colorado home to protect them from alien attacks, reports claim.
A source close to Cruise - who is a leading Scientologist - said the actor is to erect a "self-contained underground system where up to 10 people can survive for years".
The bunker will reportedly include a high-tech air-purification system and storage space for supplies and survival equipment.
Followers of Scientology are thought to believe that an evil galactic overlord named Xenu is planning to invade the planet in an act of revenge.
