It’s been quite a while since we visited Middle-Earth on the big screen (anime aside), but it looks like Lord of the Rings fans have plenty to look forward to in the coming years. We already knew that Andy Serkis’  was in the works — and by all accounts is progressing nicely — but another Rings-related film is in development too, and it’s being co-written by none other than Stephen Colbert.

The came from Peter Jackson himself, in a video posted by Warner Bros. to coincide with Tolkien Reading Day. The director of the Lord of the Rings trilogy provided a quick update on Serkis’ film (the British actor is both directing and reprising his role as Gollum), before introducing “very special partner” and diehard Tolkien fan Colbert on a video call.

With The Late Show nearing its end, its host was seemingly going to be out of work in the summer. Colbert is working with his son Peter as well as screenwriter Philippa Boyens (who co-wrote the original film trilogy). They’ll adapt some early chapters of Fellowship of the Ring that never made it into Jackson’s 2001 film. The Lord of the Rings: Shadow of the Past is actually set 14 years after the events of Return of the King, and will see Sam, Merry and Pippin retrace the first steps of their famous adventure.

So while the new film is inspired specifically by Fellowship chapters III (‘Three is Company’) through VIII (‘Fog On The Barrow-Downs’), it sounds like we’re actually getting a sequel of sorts, in which we’ll also see Sam’s daughter Elanor make a huge discovery that puts her on her own quest.

Colbert and his son had been scribbling away at their idea for several years before plucking up the courage to show what they had come up with to Jackson, but the legendary 64-year-old filmmaker was clearly a fan. And given the timing of the announcement, Colbert will soon be able to commit all of his energy to the project, which has not yet named any cast members. Will Sean Astin, Billy Boyd and Dominic Monaghan be dusting off their hobbit attire? Only time will tell, but the time jump would presumably make it possible.

The Lord of the Rings: Shadow of the Past doesn’t have a release date, but its announcement coincides with the 25th anniversary of Fellowship of the Ring, which has already been by the whole trilogy returning to theaters earlier this year.
