Given Jurassic World: Fallen Kingdom brought in Jeff Goldblum’s Ian Malcolm and there are hints Jurassic World 3 will bring back some of the rest of the original cast, another reboot down the line could always bring Bryce Dallas Howards Claire Dearing and Chris Pratt’s Owen Grady back into play.
(Seriously, though, there’s been so much talk about other original cast members returning.)
Honestly, however, I don’t necessarily anticipate this will be the last movie the franchise as a whole ever makes.
