Despite Steven Spielberg being keen to get a sequel made, t's been ten years since the last Jurassic Park outing. But dino fans fear not; the fourth movie is in development.
But according to producer Kathleen Kennedy, they haven't quite cracked the story yet.
"It's really hard to keep these things going when there's an expectation and a desire by the public and the audience to keep certain franchises going," she told ComingSooon.net.
"As filmmakers, we often sit there going, 'Okay. We have to answer the question, 'Why do another one?'' If you can't answer that question, you shouldn't be doing it. It's tough.
"We're trying to come up with a story that makes sense and isn't going to disappoint people and is, hopefully, going to get people excited and reinvigorate the franchise. We've got to start with a script and the story."
Kennedy is, more often than not, the producer on Spielberg's films, including his up-coming bio-pic, Lincoln.
"We've worked on this over a decade now," she said of the bio-pic.
"We were trying to finesse the script and get to a place where we felt we were ready to shoot. It has always fascinated Steven."
She was also willing to comment on another title she's helping bring to life - a new adaptation of Roal Dahl's The BFG.
"It's live action, and the project is pretty far along," Kennedy explained.
