O Mundo Perdido: Jurassic Park

In 1995, director Steven Spielberg met Vanessa Chester at the premiere of A Princesinha (1995), in which she appeared. Chester later recalled, "As I was signing an autograph for him, he told me one day he'd put me in a film." Spielberg met with Chester the following year to discuss this movie before ultimately casting her as Malcolm's daughter, Kelly.

(at around 1h 50 mins) After Ian and Sarah have the infant T-Rex in the back seat of the red convertible, as Ian turns into the gas station, in Ian's rear-view mirror you can see a brief reflection of Steven Spielberg with baseball cap directing the scene.

David Koepp is listed as the "unlucky bastard" because he was eaten by the T-Rex. Koepp wrote the screenplay.

The Fox television network's version (aired on November 1st, 1998) includes two scenes not in the theatrical cut (see Trivia section). The first scene is an InGen meeting between Ludlow and InGen representatives, and takes place in between the opening Compy attack sequence and the Hammond scene. It contains exposition about what aftereffects the events of the first film had on InGen, and how Ludlow is taking over control of the company from Hammond. The second is in between the Hammond scene and the mission-prep scene with Eddie Carr. Set in Mombasa, it introduces Roland Tembo and Ajay Sidhu and makes it clear they have a long history working together. Both deleted scenes are included as special features on the DVD and Blu-ray, but are not integrated into the film.
