Jurassic World Dominion sees the return of the three main actors from 1993's Jurassic Park, namely Laura Dern, Jeff Goldblum and Sam Neill, who are reprising their roles as paleobotanist Dr Ellie Sattler (presently a soil and climate change scientist), paleontologist Dr Alan Grant and Goldblum’s mathematician Dr Ian Malcolm.
Goldblum, who had returned as Dr Malcolm for a small scene in 2018's Jurassic World: Fallen Kingdom, said this of the reunion in Dominion: “I was so excited. You could have knocked me over with a feather. Is that the expression? Yeah, I was very excited.
