Filming has begun on the four sequels to Avatar , James Cameron’s 2009 3-D CGI adventure about a paraplegic marine who lands on the planet Pandora to mine unobtainium. This time, though, Cameron is really gonna make it happen — he’s not playing around! He’s spent much of the last decade teasing us about the upcoming installments, throwing out piecemeal updates (with occasional breaks for a Titani c rerelease or to shade Alien: Covenant ). But this time, he’s serious.

Avatar 2 is just the first of the installments known as the The Avatar Sequels , which will come with a budget of $1 billion. (That’s three and a half Lord of the Rings trilogies, six Wonder Woman s, 66 Hurt Locker s, and 250 Moonlight s.) On August 9, Cameron, Sam Worthington, and Zoe Saldaña announced at D23 Expo that the third Avatar film will be called Avatar: Fire and Ash.

Below, a timeline of all Cameron’s Avatar promises that once seemed broken, or at least teetering on the edge of breaking, but he’s definitely about to make good on them, you’ll see. You’ll all see. January 7, 2010: Days after Avatar made $1 billion , Cameron announces that we’re getting a sequel.

“Yes, there’ll be another,” he tells the crowd after a screening in Los Angeles. January 14, 2010: Now he says there won’t just be another — there will be several more. “I’ve had a story line in mind from the start — there are even scenes in Avatar that I kept in because they lead to the sequel,” he tells.
