The director's 1993 monster hit, starring Sam Neill and Jeff Goldblum and based on the book by Michael Crichton, spawned two sequels. However, Spielberg stepped away from the camera and acted only as executive producer on the last film, 2001's Jurassic Park III, which saw Neill return to the dinosaur franchise.
The legendary moviemaker has now confirmed work has begun on a new installment, telling Empire magazine, ""The screenplay is being written right now by Mark Protosevich. I'm hoping that will come out in the next couple of years. We have a good story. We have a better story for IV than we had for III.""
