Ellie Sattler
Jurassic Park character
portrayed Dr. Ellie Sattler, a paleobotanist, in Steven Spielberg's 1993 film Jurassic Park, a role that brought her international recognition. She reprised the role in Jurassic Park III (2001) and Jurassic World Dominion (2022), becoming a central figure in the franchise. Dern was Spielberg's first choice for the character, influenced by her performances in Smooth Talk and Rambling Rose, and was drawn to the role because of its strong, independent, and intelligent portrayal of a woman in science. The character's romantic connection with Dr. Alan Grant, played by Sam Neill, was portrayed despite a 20-year age gap between the actors, which neither actor found problematic during filming.
Factsheet
I've often wondered if Ellie Sattler was in the book or in the original script because the impression I got was it was more about Alan Grant and his bond with the kids. Ellie got sidelined after the 1st act and one had to wait until the final act for her to come back and do anything.
I wasn't even disappointed when Alan and Ellie came back for Jurassic Park III and he was the lead and Ellie settled with a glorified cameo.
I do wonder if her limited role in JP was a way for the age difference to not be obvious because Dern was 25 and Neil was 46 and I didn't notice at first, though the more I see JP, the more noticeable it gets.
