Rex Features

Producer Kathleen Kennedy has admitted that Jurassic Park 4 is unlikely to come to fruition.

Speaking to Coming Soon, Kennedy disclosed that she, partner Frank Marshall and Steven Spielberg are no longer developing a sequel to the dinosaur adventure series.

She said: "No... I don't know. You know, when [author Michael] Crichton passed away, I sorta felt maybe that's it. Maybe that's a sign that we don't mess with it."

Universal previously hired William Monahan and John Sayles to write scripts for a fourth instalment in the franchise.
