Cameron insisted of any criticism surrounding the first film, “The trolls will have it that nobody gives a s**t and they can’t remember the characters’ names or one damn thing that happened in the movie.

“Then they see the movie again and go, ‘Oh, OK, excuse me, let me just shut the f**k up right now.’ So I’m not worried about that.”

Cameron also discussed the movie’s running time, with the original flick clocking in at 160 minutes, while “The Way of Water” is expected to last around three hours.

The director told the mag, “I don’t want anybody whining about length when they sit and binge-watch [television] for eight hours.

“It’s like, give me a f**king break. I’ve watched my kids sit and do five one-hour episodes in a row. Here’s the big social paradigm shift that has to happen: it’s OK to get up and go pee.”

A synopsis for the upcoming film reads, “Jake Sully [Sam Worthington] lives with his newfound family formed on the planet of Pandora. Once a familiar threat returns to finish what was previously started, Jake must work with Neytiri [Zoe Saldana] and the army of the Na’vi race to protect their planet.”
