Avatar 2 is expected to reach theaters in December 2018, followed by Avatar 3 in December 2020, Avatar 4 in December 2022, and Avatar 5 in December 2023.
Worthington, in case you had forgotten at this stage, is reprising his role from the first Avatar in the sequels, as is Zoe Saldana, Sigourney Weaver and Stephen Lang.
In other words: even after all these years, it’s still not wise to bet against Cameron pulling off his four-part Avatar sequel trick.
Of course, as Cameron put it when confirming Lang’s return for the Avatar sequels (all the way back in October of 2013), “It’s a science-fiction story, after all.”
