With shooting finally starting of James Cameron’s sequels to Avatar, a few new cast members are coming onbaord to join the likes of Sam Worthington, Zoe Saldana and Signourney Weaver (or at least their motion-captured forms). Now Deadline reports that one of the newcomers will be Kate Winslet, who’ll reteam with Cameron for the first time since Titanic.

The director says, “Kate and I have been looking for something to do together for 20 years, since our collaboration on Titanic, which was one of the most rewarding of my career. I can’t wait to see her bring the character of Ronal to life.”

What Cameron doesn’t reveal though is who Ronal is and how she fits into the movie. There have been few story details released, although it’s known he’s planning four sequels to be released between 2020 and 2025. The stories will introduce us to Jake Sully and Neytiri’s children, as well as other tribes of Na’vi such as the Metkayina, who live on oceanic atoll reefs.
