Ariana Richards Got The Part Of Lex In Jurassic Park Because Of Her Scream
To cast Hammond's granddaughter, Lex, Spielberg auditioned a number of girls and asked them to record their screams. Ariana Richards recalled that she won the role because she was the only one whose taped scream was loud enough to awaken a sleeping Kate Capshaw (Spielberg's wife) and send her scurrying down the hall to see if her children were all right.
