Filmmaker James Cameron takes his sweet time in developing projects, but when you have a resume that includes films like The Terminator, True Lies, and The Abyss, not to mention the two highest grossing movies of all time, you can pretty much do whatever the hell you want. Currently, Cameron is fine-tuning the screenplays for the Avatar sequels—Avatar 2, 3, and 4—which he intends to shoot simultaneously in anticipation of release in 2017, 2018, and 2019, respectively.

While the development period for the follow-ups has been lengthy, it looks like production will finally be getting underway later this year, and when Perri recently spoke with Sigourney Weaver in anticipation of the sci-fi pic Chappie, the actress discussed her return to the world of Pandora and the challenge of shooting all of the sequels at once.

When asked whether she’s approaching the lengthy shoot as either daunting or exciting, Weaver admitted it’s a mix of the two but went on to praise Cameron’s plans:

“I think both (laughs). I can’t wait, I have a wonderful part that he’s written for me, and it’s a part that’s gonna go through a lot of changes. I’ll be curious to see how he can just logistically manage to shoot all three films at once. But I’m very excited to be part of this continuing message he wants to bring our planet. From the artwork he’s shown me, it’s just mind-blowing. And frankly the more time he takes with these scripts, probably the better movies they’ll be.”

I’m incredibly curious not only to see what Cameron’s plans for the sequels entails, but also how the general public greets the follow-ups. The filmmaker is nothing if not ambitious, and by shooting three movies at once, Cameron is poised to make this his biggest challenge yet.
