Steven Spielberg's next movies are Indiana Jones 4 & a biography of Abraham Lincoln, but that doesn't mean Spielberg isn't thinking of a new science fiction project!
It has been sometime now that Spielberg has been thinking of a space theory by theoretical physicist Kip S. Thorne, something about the existence of Wormholes & that they present a realistic opportunity for time travel.
This project would be venturing out farther than anything he's made previously.
Spielberg plans to direct the picture himself in partnership with Paramount Pictures.
