Peter Jackson's next big film project has been announced - and it's not another Hobbit movie.
This time Jackson will be losing his director's hat and producing an adaptation of Philip Reeve's first novel from his sci-fi fantasy book series, Mortal Engines.
According to the Hollywood Reporter, Jackson will be handing over directorial duties to his long-time protégé Christian Rivers, with Mortal Engines marking his solo debut.
The Mortal Engines series is set in the distant future after a war has all but destroyed the Earth and cities have been transformed into mobile machines battling for resources.
Jackson is reported to have written the script for the film in a three-hander with his wife, Fran Walsh, and Philippa Boyens - both of whom performed a similar role on the Lord of the Rings and Hobbit franchises.
Of passing the reins over to Rivers, Jackson said: "Christian is one of my closest collaborators. The combination of emotion and jaw-dropping visuals in Mortal Engines makes this the perfect movie for his move into feature directing.
"What Christian intends to do with Philip Reeve's terrific story is going to result in an original and spectacular movie. I wish I could see it tomorrow!"
