Steven Spielberg is going out of this world for his latest film project.

The "Munich" helmer will direct an untitled sci-fi movie that will centre on a group of space explorers who travel through a wormhole and into another dimension, Variety reports.

Spielberg became interested in the real science theory that wormholes can be used as time travel portals when he attended a workshop that discussed the controversial theory.

Since the project will take several years to develop, Spielberg will keep himself busy by helming the fourth installment of "Indiana Jones," and taking the reins of an Abraham Lincoln biopic starring Liam Neeson.
