The film stars Chris Pratt, Bryce Dallas Howard, Vincent D'Onofrio, Ty Simpkins, Nick Robinson, Omar Sy, BD Wong, and Irrfan Khan.

A successful theme park of cloned dinosaurs, dubbed Jurassic World, has operated on the island for years, bringing John Hammond's dream to fruition.

Universal Pictures intended to begin production of a fourth Jurassic Park film in 2004 for a mid-2005 release, but the project lingered in development hell while the script underwent several revisions.

Brothers Zach and Gray Mitchell visit Jurassic World, a dinosaur theme park on Isla Nublar, of which their maternal aunt Claire Dearing is the operations manager.

Elsewhere on the island, Navy veteran and ethologist Owen Grady has been training a Velociraptor squad composed of Blue, Charlie, Delta, and Echo, and researching their intelligence.

Based on the raptors' ability to follow commands, the head of InGen security Vic Hoskins believes that the animals can be weaponized, an idea Owen and his assistant Barry vehemently oppose.

Claire and Jurassic World owner Simon Masrani inspect the park's newest upcoming attraction, the Indominus rex, a transgenic dinosaur created by geneticist Dr. Henry Wu.

A team of experts, including Dr. Alan Grant and Dr. Ian Malcolm, would chart an expedition to an offshore island and discover the dinosaurs breeding freely.

[36] In one draft, a new character, a mercenary named Nick Harris, would be charged with training a team of genetically modified Deinonychus for use on rescue missions and to combat drug dealers.

[21][66][67] Between 2003 and 2008, several cast members from previous Jurassic Park films were expected to reprise their roles, including Sam Neill as Dr. Alan Grant,[68] Jeff Goldblum as Dr. Ian Malcolm,[69][70] Richard Attenborough as John Hammond,[71][72] and Laura Dern as Dr. Ellie Sattler.

[22] Trevorrow and Connolly did not want to bring back the other characters unless there would be a good reason for them to be involved in the story; they considered Dr. Henry Wu, the scientist responsible for recreating dinosaurs, a logical choice.

[112][113] The theme park website featured a high level of fictional detail, including hotel accommodations, weather reports and wait times for rides.

Trevorrow stated that because of the film's cost, the trailers included scenes Universal felt were necessary to ensure its financial success after the studio's disappointment with Jurassic Park III's box-office performance.

[131] Companies including Kellogg's, Dairy Queen and Barbasol served as promotional partners for the film,[132] and Lego and Hasbro released toys based on it.

[137][138] Tippett Studio worked with Universal and Efexio to create an application titled "Jurassic World Mobile MovieMaker",[139] which adds images of dinosaurs to a background photograph.

[173] Deadline Hollywood calculated the film's net profit as $474 million, accounting for production budgets, marketing, talent participations, and other costs; box office grosses and home media revenues placed it third on their list of 2015's "Most Valuable Blockbusters".

[158] On its fourth day of release, Jurassic World made $25.6 million, making it the third-highest Monday gross, after Spider-Man 2 and Indiana Jones and the Kingdom of the Crystal Skull.

[187] The film set a record for the largest second-weekend gross, its revenue dropping by 49% to $106.6 million[188][189] and it topped the North American box office for three consecutive weekends.

[197][179][198][142] Until Sunday, June 14, it had a five-day opening weekend total of $316.1 million from 66 countries from 19,612 screens, representing 31% of its overseas gross and setting an opening-weekend record, surpassing Harry Potter and the Deathly Hallows – Part 2.

Its critical consensus reads: "Jurassic World can't match the original for sheer inventiveness and impact, but it works in its own right as an entertaining – and visually dazzling – popcorn thriller".

[179] Peter Bradshaw of The Guardian gave the film four stars out of five and said it is a "terrifically enjoyable and exciting summer spectacular" and "savvy, funny, ridiculous in just the right way".

[218] Robbie Collin of The Telegraph also awarded it four stars, deeming it a worthy sequel to the original Jurassic Park and calling it "methodically paced and shot with an awestruck visual sense that's pure Spielberg".

[222] David Crow, writing for Den of Geek, considered Jurassic World a legacy sequel and wrote that it gave fans "everything they loved about the first one without trying to change things up".

[223] The Associated Press praised Pratt and Howard's performances but rated the film two stars out of four, calling it "an ugly, over-saturated movie" that lacks the "deft sense of wonderment, wit and suspense that guided the original".

[224] Ann Hornaday of The Washington Post also rated it two stars out of four, writing "every action movie today ends up as Transformers and, even when it's cloned creatures fighting, the same is true here (with an antic dash of "Sharknado" tossed in for good measure).

[227] Several news publications, as well as Neill, noted the violence of the franchise's first notable depiction of a woman being killed onscreen,[85][228][87] and Entertainment Weekly wrote: "There's nothing amusing about the demise of Zara, who's as close to 'real people' as Jurassic World gets, and it's that unsettling quality about her death that more Hollywood disaster epics need in order to reclaim their visceral emotional prowess".

[247] The film also explores animal rights concepts; the Indominus rex was raised in captivity and in complete isolation, making the creature "not fully functional".

Several paleontologists called the film a "dumb monster movie" for failing to include new discoveries about the creatures; for example, the feathers or proto-feathers that covered some dinosaurs and the way Velociraptor held its front limbs.

[260][261] At the end of March 2015, a Writers Guild of America (WGA) arbitration panel ruled that Trevorrow and Connolly would instead share a "screenplay by" credit with Jaffa and Silver.

Despite a difference of opinion on the final credits, Trevorrow said he and Connolly were on peaceful terms with the earlier writing team: "Though we may not agree on the specifics of this ruling, we share a disdain for the arbitration process and the ugliness it often breeds.
