John Hammond (Richard Attenborough) is the owner of Jurassic Park, a theme park located on Isla Nublar. When an incident with a velociraptor results in the death of an employee, Hammond brings in three specialists to sign off on the park to calm investors. The specialists, paleontologist Alan Grant (Sam Neill), paleobotanist Ellie Sattler (Laura Dern), and chaos theorist Ian Malcolm (Jeff Goldblum) are surprised to see the island park's main attraction are living, breathing dinosaurs, created with a mixture of fossilized DNA and genetic cross-breeding/cloning. When lead programmer Dennis Nedry (Wayne Knight) shuts down the park's power to sneak out with samples of the dinosaur embryos to sell to a corporate rival, the dinosaurs break free, and the survivors are forced to find a way to turn the power back on and make it out alive. The film also stars Bob Peck, Martin Ferrero, BD Wong, Ariana Richards, Joseph Mazzello, and Samuel L. Jackson.
Jurassic Park is regarded as a landmark in the use of computer-generated imagery and received positive reviews from critics, who praised the effects, though reactions to other elements of the picture, such as character development, were mixed. During its release, the film grossed more than $914 million worldwide, becoming the most successful film released up to that time (surpassing E.T. the Extra-Terrestrial and surpassed 4 years later by Titanic), and it is currently the 17th highest grossing feature film (taking inflation into account, it is the 20th-highest-grossing film in North America). It is the most financially successful film for NBCUniversal and Steven Spielberg.
Jurassic Park had two re-releases: The first on September 23, 2011, in the United Kingdom and the second in which it was converted into 3D on April 5, 2013, for its 20th anniversary, which resulted in the film passing the $1 billion mark at the worldwide box office.
