Whether or not you choose to believe the filmmaker depends on just how much caution you want to attach to your optimism. Cameron discussed his progress on the follow-up flicks in a recent interview with The Daily Beast, and noted that he's devoted a significant amount of time and attention to each film, perhaps explaining why it's taken so long to get these movies off the ground.
Here's what he told The Daily Beast:
" ... My focus is on Avatar 2, 3, 4, and 5 equally. That's exactly how I'm approaching it. They've all been developed equally. I've just finished the script to Avatar 5. I'm now starting the process of active prep. I'll be working with the actors in the capture volume in August, so I'm booked in production every day between now and then. Our volume is up and running, and everything is designed, and so we're going full-guns right now. I feel like I've been let out of jail, because I've been in the writing cave for the last two years. I'm actually enjoying life. I don't enjoy writing. I wouldn't wish writing on a dog."
So perhaps Cameron's desire to get everything just right is what caused such a massive delay in production. (And his aversion to writing probably played a role, too.) According to star Sigourney Weaver, all the extra time the filmmaker spent on the scripts appears to be worth it. Audiences will hopefully get to be the judge of that themselves soon.
"Avatar 2," "Avatar 3," "Avatar 4," and "Avatar 5" are currently slated for release around Christmas in 2018, 2020, 2022, and 2023.
