Titanic star Kate Winslet has just boarded James Cameron's Avatar franchise. Deadline reports that Winslet will reteam with Cameron for Avatar 2, which just recently kicked off production.

The actress has reportedly signed on for the "ongoing" Avatar adventure, and -- while the report was unable to specify just how many films she will appear in -- it's worth noting Cameron has four sequels planned. “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,” Cameron said. “I can’t wait to see her bring the character of Ronal to life.”

The long-delayed Avatar sequels are expected to shoot consecutively, with production having kicked off last month. Each sequel is envisioned as a standalone movie that will ultimately tie together to form a family saga.

Cameron directed the two highest grossing films ever. 1997's Titanic snagged an impressive $2.1 billion at the worldwide box office and remained the highest grossing film until 2009's Avatar finished its theatrical run at an astonishing $2.7 billion dollars at the worldwide box office.

The Avatar franchise imagines a distant future in which Earth’s natural resources have been depleted. In the first film, a mining company from Earth sets off for a planet called Pandora, inhabited by tall, blue creatures called Na’vi, to mine a rare mineral dubbed unobtanium. Human miners pilot Na’vi-human hybrids to explore the world, and one of those pilots, Jake Sully, comes to find he likes the Na’vi way of life more than the human. Jake leads a rebellion against the miners, driving back their advances.

Debuting in theaters on December 18, 2020, the first of the Avatar sequels is only the beginning. The franchise has films planned for as far out as 2025.
