In other words: these people are comedy actors, not unlike the film's star, Chris Pratt, whom we all know and love for being a comical buffoon on Parks and Recreation and aw-shucksing his way through space as Peter Quill in Guardians of the Galaxy. They also threw Jake Johnson from New Girl and Drunk History into the mix. Even the director of Jurassic World, Colin Trevorrow, has only one previous feature credit to his name: the independent comedy Safety Not Guaranteed. That's like hiring the cast of Saturday Night Live to make a Jaws sequel.
This one, specifically.
For an adventure-thriller, that entire lineup makes zero sense. But if Jurassic World is secretly a hijinks-laden comedy romp, that lineup is a goddamned treasure chest of chuckles. Who wouldn't want to see Star Lord bumbling his way through an encounter with an angry T-rex?
Apparently not the studio, because Pratt has already gone on record saying that his character is "deadly serious" and "not like Peter Quill," despite being required to deliver lines like "Depends on what kind of dinosaur they cooked up in that lab" with a straight face, like he's Leslie Nielsen in a Jurassic Park spoof.
