It’s a Jurassic World, and we’re all just living in it.

The highly-anticipated return of the Jurassic Park franchise was indeed highly anticipated. Jurassic World made $204 million this weekend in the United States and $511 million worldwide, making it the single-highest worldwide opening in history. The previous record-holder was Harry Potter and the Deathly Hallows, Part 2 ($483.2 million).

Adding to the already-impressive situation, Jurassic World topped this summer’s Avengers: Age of Ultron, which had opened with $191 million in May. World now sits at #2 on the list of highest grossing domestic openers with $204 million (behind the first Avengers film which made $207 million).

Jurassic World blew away all tracking expectations. Why such a big and unexpected box office? Clearly the moviegoing public has more interest in dinosaurs and nostalgia for Jurassic Park than we thought. Those who saw the original Jurassic Park in 1992 were apparently very interested in seeing a new installment and hoping for the same magic captured by Steven Spielberg. For the most part, people were pleased with the new movie: Jurassic World scored an “A” Cinemascore rating with moviegoers this weekend.

Another reason for the success could be that kids and young adults who grew up watching Jurassic Park at home wanted to catch a new installment in theaters.

A third reason? Dinosaurs. Dinosaurs.

With that kind of box office, a sequel to Jurassic World is all but official at this point — an announcement could come from Universal as early as Monday. Our resident Jurassic fan has already shared his plot ideas for Jurassic World 2.

The hype around dinosaurs is now at a fever pitch. It’s great news for Pixar, who’s releasing their own dinosaur film this November.
