Just last week, Jurassic Park 4 director Colin Trevorrow (Safety Not Guaranteed) tweeted a picture of the first film's setting, Isla Nublar.  However, the dinosaur embryos may be going into cold storage for a little bit.  AICN recently picked up some tweets from some members of the crew.  Concept Artist Dean Sherriff tweeted "JP4 on hold" while Digital Assets Manager Todd Smoyer was a bit more harsh by tweeting "Hollywood makes and crushes dreams.  Goodbye JP4".  Despite Smoyer's depressing tweet, Jurassic Park 4 is reportedly still underway, and the hold is to make the production even bigger.

Hit the jump for more. [Update: Universal Pictures has confirmed that JP4 has been put on hold indefinitely.  Read the studio's statement after the jump, along with news regarding which actors had met for the lead roles.]

[Update: The folks over at Variety add that filmmakers had met with Bryce Dallas Howard and David Oyelowo for lead roles, but negotiations had yet to begin. Here's the statement from Universal, followed by our original story:]

"In coordination with filmmakers, Universal has decided to release Jurassic Park 4 at a later date giving the studio and filmmakers adequate time to bring audiences the best possible version of the fourth installment in Universal’s beloved franchise.  We could not be more excited about the vision that Colin Trevorrow has created for this film, and we look forward to watching as he and the producers create another great chapter in this franchise's storied history."

According to Jurassic Park 4 News, the oft-cited creative differences have arisen, but the differences come from the studio wanting to make the picture bigger rather than slashing the budget:

It is this "EPIC" demand by the studio however, which has lead to the current situation. It seems Universal wants to pull out all the stops and go above and beyond what they had initially set their goals to be.

That sound great, but then the site's story gets a bit confusing.  JP4 News says that most of the concept art has already been done and that the script is not the issue.  But how can Universal make the picture bigger without changing those aspects?  If it's simply a matter of creating bigger set pieces, you still need artists to lay it out, and possibly a writer to make those set pieces fit organically into the story.  The set-up for a raptor attack can't be the same set-up for a T-Rex attack.

Despite the delay, Jurassic Park 4 is currently holding to its release date of June 13, 2014.
