Amazing Jurassic 4 plot details rumoured

Though there's been a few issues along the way – including the not inconsiderable delay in production announced last month – it seems that 'Jurassic Park 4' is now back on track.

Last week, it appeared that Universal Pictures had set a 2015 release for the film, and now some tantalising plot rumours have dropped.

Though we should stress that these are so far unconfirmed, they sound pretty damned exciting, not to mention potentially spoiler-laden, so if even rumoured spoilers aren't your thing, look away now...

The previous films had largely shown the regenerated dinosaurs running amok, but the potential set up for the new sequel may lull the audience into a false sense of security.

Film site JoBlo, which has the scoop, explains the premise thusly: “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 dinos for the first time. No indication of what kind, but there’s concept art showing one of the aquatic dinos, 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.”

Of course things then go awry, but there is also talk of tamed dinosaurs, and the possibility of velociraptors assisting humans in combatting a terrifying, intelligent new breed of dinosaur.

The writers behind the excellent 'Rise of the Planet of the Apes' Rick Jaffa and Amanda Silver have penned the script, with Steven Spielberg said to be personally working with the producers and director Colin Trevorrow on the film at the moment.

Trevorrow had previously tweeted test shots of Isla Nublar before the announcement that the production was being delayed, suggesting that it could indeed be the location for the new film.

Universal confirmed the delay last month after crew-members started tweeting that there were issues with production.

It's now hoped to be out some time in 2015.
