It's now official. The 4 sequels will be filmed at the same time starting in August.
Here's the news straight from JC:
"The thing is, my focus isnít on Avatar 2. My focus is on Avatar 2, 3, 4, and 5 equally. Thatís exactly how Iím approaching it. Theyíve all been developed equally.
Iíve just finished the script to Avatar 5. Iím now starting the process of active prep. Iíll be working with the actors in the capture volume in August, so Iím booked in production every day between now and then.
Our volume is up and running, and everything is designed, and so weíre going full-guns right now. I feel like Iíve been let out of jail, because Iíve been in the writing cave for the last two years. Iím actually enjoying life. I donít enjoy writing. I wouldnít wish writing on a dog.Ē
