The "Safety Not Guaranteed" filmmaker said that he is hoping to strike a balance between a sequel that pleases fans and a movie that introduces newcomers to the series, reported Digital Spy.
"It's important to make a movie for the fans but I also have to remember that there's a lot of people who just couldn't care less and need me to make a solid case for why the hell there's a Jurassic Park 4 in the first place, and I want to make a movie for them too.
Trevorrow recently confirmed that the upcoming instalment will introduce a new "badass" dinosaur to the fold, but refused to confirm its identity.
"Jurassic Park 4", which will be filmed in 3D, is tentatively scheduled for a 2015 release.
