Jurassic Park is one of the most famous and most successful films ever made. Its plot involves dinosaurs, of course, and it also stars two children. Indeed, Lex and Tim, played by Ariana Richards and Joseph Mazzello, were an important part of the movie. The franchise eventually moved on without them, however, as they don’t appear in the new Jurassic World movies. And they’re both fully grown adults now who are carrying on with their lives.
Lex and Tim are menaced by dinosaurs throughout all of Jurassic Park. But don’t worry – they come out of it alive. The siblings are initially invited to Jurassic Park as a distraction from their parents’ divorce. When everything goes wrong and the dinosaurs escape, though, they find a father figure in Dr. Alan Grant.
Steven Spielberg, the director of the film, needed a pair of talented children to portray Lex and Tim. And the ability to scream really well wouldn’t hurt, either. In fact, he picked Richards for the role of Lex partly on the basis of her bloodcurdling screeching. She was so good at it she terrified Spielberg’s wife Kate Capshaw.
