About 9m40s into his interview with Arnold.
"Well, COVID hit us like it hit everybody... We lost about four and a half months of production. As a result of that, we've rolled around one more full year for a release in December of 2022. That's been announced already. Now that doesn't mean I have an extra year to finish the film, because the day we deliver Avatar 2 we'll just start working on finishing Avatar 3. So where we are right now, I'm down in New Zealand shooting. We're shooting the remainder of the live action. We've got about ten percent left to go. We're a hundred percent complete on Avatar 2 and we're sort of ninety five percent complete on Avatar 3. So we're very lucky in that we chose this as our production site years ago."
