In other news, yes, there are going to be three more Avatar movies.
So here’s the skinny from James Cameron himself:
“Sigourney and I have a long creative history, dating back to 1985 when we made Aliens,” Cameron said. “We’re good friends who’ve always worked well together, so it just feels right that she’s coming back for the Avatar sequels. Her character of Grace Augustine, as fans know, died in the first movie, so she’s playing a different and in many ways more challenging character in the upcoming films. We’re both looking forward to this new creative challenge, the latest chapter in our long and continuing collaboration.”
In Avatar she dies as they are trying to perform a ritual that would transfer her consciousness from her dying human body into her avatar body permanently by way of the Na’vi people’s nature god Eywa. Given that that movie, though enjoyable, was a parade of well executed cliches, Grace is totally an aspect of Eywa in the next movies right? She and Eywa are one and Eywa turns out to be not so much a being as the connection between all living things itself and the addition of Grace adds a recognizable face to interact with right?
It’s SciFi so it could go in an entirely different direction (clones? twins? holoprojected computer version of her personality?) however I kind of don’t think it will.
It’ll be a while before we find out for sure. The three Avatar sequels will shoot back to back and are scheduled for December 2016, 2017, and 2018.
