Between 2003 and 2008, several cast members from previous "Jurassic Park" films were expected to reprise their roles, including Sam Neill as Dr. Alan Grant, Jeff Goldblum as Dr. Ian Malcolm, Richard Attenborough as John Hammond, and Laura Dern as Dr. Ellie Sattler. Attenborough retired from acting following a fall at his house in 2008. A statue of his character is featured in the film. Trevorrow and Connolly did not want to bring back the other characters unless there would be a good reason for them to be involved in the story; they considered Dr. Henry Wu, the scientist responsible for recreating dinosaurs, a logical choice.
