Rumor: 'Jurassic Park 4' Plot Details Revealed? [UPDATED]

[UPDATE: It's worth pointing out that JoBlo's story refers to Rick Jaffa and Amanda Silver as the writers of Jurassic Park 4. In fact, Trevorrow and Derek Connolly were behind the latest script rewrite. The details apparently come from an earlier draft by Jaffa and Silver that predates Trevorrow's involvement. Original story follows.]

When Universal decided to pull Jurassic Park 4 off the 2014 calendar, one of the reports floating around claimed the the delay had to do with the scope of the film. The studio apparently wanted something "epic," and wasn't confident that they could pull that off by next summer.

Now a rumored plot synopsis may offer a bit of insight into exactly how big Universal and director Colin Trevorrow were thinking. And depending on how much of it is true, their decision to extend the deadline may make a lot of sense. Get the details after the jump.

JURASSIC PARK 4, set in present day Isla Nublar, is now an actual theme park, as originally intended by John Hammond in the first film. It garners 10 million visitors per year and is completely safe – until it's not. The park itself is described as very Sea World-esque and includes an area called the Isla Nublar Lagoon. That means underwater dino's for the first time. No indication of what kind, but there's concept art showing one of the aquatic dino's, as part of a show, jumping out of the lagoon and eating a strung up great white shark like it was a fish for a dolphin at sea world.

As part of a show, you ask? That's right, folks, this will feature "tamed" dino's. In fact, our source indicated that the usually menacing Velociraptors (which will finally be muzzled, along with the T-Rex – until they're not) will actually be used to help fight the threat, which begins in the form of a new dinosaur, not seen in any of the previous films (and not disclosed to us) shows to be much smarter than originally thought and is the main cause of havoc breaking out at the park.

So, to sum it all up, JURASSIC PARK 4 will take place back on Isla Nublar with a fully operational dinosaur theme park (I'm sure no expense was spared) that's both prosperous and safe, until a new dinosaur figures out a way to wreak havoc, causing the use of the now tamed Velociraptors (and T-Rex? Unclear) as a means to fighting the threat.

Now, our own source close to production says that summary gets a few bits right, but that it's mostly incorrect. Trevorrow has previously


d that the sequel would return to Isla Nubar, so we're guessing that the location info has some truth to it. We've also


from paleontologist Jack Horner, who's consulting on the movie, that at least one new dino would appear. But otherwise, your guess is as good as ours as to which details are accurate and which are not.

In any case, the Jurassic Park franchise has always been about extravagant, ambitious, effects-heavy spectacle — and that kind of stuff tends to look shoddy and cheap if rushed. So even if JoBlo's story isn't entirely true, they may be on to something about the level of ambition. Hopefully the newly rumored 2015 date gives Trevorrow ample time to get it right.
