James Cameron claims that Avatar: The Way of Water will need to be in the top five highest-grossing movies of all time just to break even.
The second Avatar movie has been in development for over a decade following the enormous success of the first film in 2009.
On a reported budget of $237 million, Avatar earned never-before-seen box office success, earning $2.847 billion in ticket sales.
The 2009 movie saw Jake Sully (Sam Worthington), a paraplegic former marine, enter the world of Pandora and eventually fall in love with Na'vi native Neytiri (Zoe Saldana) while dealing with the insurrection from the human army, led by ruthless Colonel Miles Quaritch (Stephen Lang).
The Way of Water will need to break into the top five to earn any money, which means it will need to overcome the $2.04bn earned by Avengers: Infinity War.
"You have to be the third or fourth highest-grossing film in history," Cameron admitted to GQ.
"That’s your threshold. That’s your break even.
"I like difficult. I’m attracted by difficult. Difficult is a f****** magnet for me. I go straight to difficult.
"And I think it probably goes back to this idea that there are lots of smart, really gifted, really talented filmmakers out there that just can’t do the difficult stuff.
"So that gives me a tactical edge to do something nobody else has ever seen, because the really gifted people don’t f****** want to do it."
Avatar: The Way of Water will be released on 16 December.
