Speilberg set for space travel film

War Of The Worlds director Steven Spielberg is developing a film about a group of explorers who travel through a wormhole in space into another dimension.

Spielberg will direct the film, which is based on actual scientific research.

The idea for the film was derived from research by California Institute of Technology (Caltech) physicist Kip S Thorne, who is an expert on relativity.

Thorne is most famous for his controversial theory that wormholes not only exist, but can be accessed and used as portals for time travel.

The director was so enamoured with Thorne's theories that he attended a Caltech workshop with the physicist and other scientists.

Spielberg also brought his 89-year-old father Arnold to the workshop, who is a retired engineer.
