Also referred to as Kelly Curtis. Kelly is the daughter of Ian Malcolm and an unnamed mother during the second film. In the film script she is called "Kelly Malcolm, an African-American girl around twelve years old." Her first name comes from Kelly Curtis (a girl in the second novel) and her skin color is an allusion to Arby Benton (a boy in the second novel). The rest of her character is the creation of David Koepp. She has two other siblings that Malcolm mentions in Jurassic Park. She is notably remembered for being the first and only person to successfully kill a raptor without the use of any weapon.
In Jurassic Park: Builder Kelly studies journalism and aquatic biology. Kelly, illegally, releases footage of the dinosaurs in the park. John Hammond gives Kelly a job at the Glacier Park.
