Washington, Feb 13 : Those waiting for the third `Batman' flick might be in for disappointment, for `The Dark Knight' director Christopher Nolan has signed a sci-fi movie and won't start the next outing of the `Caped Crusader' before two years at least.

Nolan directed the comic book adaptations in 2005 with Batman Begins, and then made the 2008 box office smash `The Dark Knight'.

And now that fans are eagerly waiting for a third Batman offering by the British filmmaker, Nolan has signed up to direct futuristic offering `Inception'.

Any plans for another Batman outing will have to wait at least another two years, reports Contactmusic.

`Inception' is based on a script written by Nolan himself, and filming for it expected to start this summer.

The film's release is expected in 2010. (ANI)
