Also says that whilst the capture work is all completed, he has 5 months of live action shooting still to complete this year.
Talking for a very special Empire Podcast documentary for Empire 30 – a 30-minute Avatar making-of, featuring brand new interviews and insights – the filmmaker revealed some interesting tidbits about the highly-secretive sequel. For one, it's set several years on from the 2009 original – Jake and Neytiri are still together, and they now have an eight year-old daughter. Cameron detailed a 'critical' argument scene between the bickering parents, shot from the point of view of their kid – all part of the 'emotional rollercoaster' that Jake faces in the coming instalments.
"There's a three-page argument scene between Jake and Neytiri, a marital dispute, very, very critical to the storyline," Cameron explains on the Avatar Podumentary. "I wound up shooting it all from the point of view of the eight year old hiding under the structure and peeking in […] Having gone through the experience with [Sam Worthington] on Avatar, I now knew how to write the Jake character going forward across the emotional rollercoaster of the next four movies. It's been tough on him. He's done two pictures back to back now, because we did 2 and 3 together. He had to go to some dark places."
