Zack Sharf Digital News Director When James Cameron’s fifth “Avatar” movie opens in theaters in 2031, Zoe Saldaña will end a whopping 26-year journey playing the Na’vi warrior and devoted mother Neytiri. How’s that for character longevity? Disney announced June 13 that Cameron’s three upcoming “Avatar” sequels have been pushed back on the release calendar yet again, extending the franchise into 2031. “Great! I’m gonna be 53 when the last ‘Avatar’ comes out,” Saldaña humorously posted on her Instagram alongside a shocked face emoji. “I was 27 when I shot the very first ‘Avatar.'” Saldaña’s co-star Sam Worthington, who stars as Jake Sully in the franchise, will be 55 years old when the final “Avatar” movie hits theaters. Cameron will be 77 years old.
