In case it weren’t obvious what the rating would be already, the MPAA has officially rated Jurassic World PG13 in the United States, citing “intense sequences of science-fiction violence and peril”. Not really a surprise considering the last three films were PG13 too. Don’t worry, there’ll still be plenty of creature violence.
There’s no word on what the rating will be in the UK, but the previous three Jurassic Park films were all PG. I wouldn’t be surprised if this were a 12, though.
