There’s a bunch of Avatar sequels on the way. Eventually. We’ve been hearing about a sequel to Aliens and Terminator 2: Judgment Day director James Cameron‘s record-smasher for years, but the second movie has been delayed multiple times.

Creeping up on a decade since the original was released, the sequels are starting to take shape once again. Last month, release dates for the four sequels were set again, with the first now scheduled for release in 2020—11 years after the original was released. And now a new actor has joined the cast. Fear the Walking Dead star Cliff Curtis has signed on for one of the lead roles in the sequels.

If you loved Bong Joon Ho‘s English-language debut Snowpiercer that was on many year-end favorites lists, including the lists of some of Geeks of Doom’s own contributors, more stories set in that world might be on the way.

It’s being reported that the rights to the film have been optioned, with the intention of adapting it into a new TV series. Marty Adelstein‘s Tomorrow Studios optioned the rights to adapt the movie into a new show, and Josh Friedman has been set to write the script.

Yesterday, we learned that Terminator: The Sarah Chronicles creator Josh Friedman was tapped to write the sequel to James Cameron‘s long-gestating sequel to Avatar. This was the first real sign that production was moving forward for the film.

Now comes word that Cameron isn’t only bringing in Friedman, but multiple other screenwriters to work on not one, but three sequels. Avatar 2, Avatar 3, and Avatar 4 will be shot simultaneously starting next year, and Avatar 2 will hit theaters December 2016.

James Cameron wrote and directed 2009’s Avatar, which would go on to become the biggest box office movie of all time, so you would expect him to also write and direct the long awaited sequel, Avatar 2. But it appears that Cameron will instead have others pen the follow-up, or at least work with him in crafting a draft or two.

According to a source close to Fox, Cameron has brought in Josh Friedman to work on the script for the sequel. Friedman created the Fox TV series Terminator: The Sarah Connor Chronicles—based on the Terminator movie franchise, of which Cameron directed the first two installments — and has also worked on the screenplays for Steven Spielberg’s War of the Worlds and The Black Dahlia, as well as the teleplay for the Locke & Key series that never came to be.
