Laura Dern is back as Dr Ellie Sattler in Jurassic World Dominion, and the film's environmental message really struck a chord with the star.
Dern had not played Sattler since a brief appearance in 2001's Jurassic Park III, which she shot in a single day, but was enticed back for director Colin Trevorrow's epic trilogy-closer.
The 55-year-old Oscar winner told Yahoo that she did not have misgivings about the prospect of coming back and once again sharing the screen with Jurassic Park co-stars Sam Neill and Jeff Goldblum.
Jurassic World Dominion arrives in IMAX and cinemas across the UK on 10 June.
