Answer: Laura Dern
Dern, a native of Los Angeles, California, played Dr. Ellie Sattler. Dr. Sattler was a paleobotanist and was thrilled when she and Dr. Alan Grant were invited to go see genetically created dinosaurs on Jurassic Park. When they first started exploring the island, they came upon a brontosaurus and Ellie was amazed at how big the dinosaur was. Upon further exploration of the island, Ellie and others came upon a triceratops that was sick. Ellie decided she would stay behind, to help the triceratops and she told Dr. Grant she would meet him at another location. Ellie went to where the T-rex exhibit was and noticed it had escaped, so she and someone else continued to look around. They came upon an injured Ian Malcolm and got him in their jeep and drove off. While they drove, a T-rex charged after them and tried to flip the car over but was unsuccessful. Meanwhile, the power to the park went out and Ellie decided she would go to a building and turn it on, so John agreed to provide her instructions to do it. Ellie turned the power on and it was right after she did that that she encountered a velociraptor but, she was not injured by it. Dern reprised her role of Ellie Sattler in "Jurassic Park III", She was also in the movies, "I Am Sam" and "Citizen Ruth". In 1992, she was nominated for Best Actress in a Leading Role for the film "Rambling Rose", but she lost to Jodie Foster for "The Silence of the Lambs". Other Oscar nominees for Best Actress in a Leading Role that year were Bette Midler for "For The Boys", Geena Davis for "Thelma and Louise" and Susan Sarandon for "Thelma and Louise".
