Steven Spielberg has confirmed he will not be directing Jurassic Park 4.

The War Horse director - who helmed the first two stories in the dinosaur movie series - will be returning for the mooted fourth installment, but only in the capacity of producer: "I don't want to talk about Jurassic Park 4 yet - it's too early - but I can tell you that I'm not directing it. I'm producing it though."

Steven also confirms his forthcoming adaptation of Daniel H. Wilson's Robopocalypse will be a "big popcorn movie," but does not want to confirm too many details about the project. He added at a press conference in Paris, "I'm making a science fiction movie probably in September called Robopocalypse because on Daniel Wilson's book. It's a cautionary tale about war between human beings and robots. It's a big crowd pleaser, I think, a big action popcorn movie with a message. I have a couple of other plans which I don't want to go into because they're too far out of the horizon."
