A director has been tapped for a fourth Jurassic Park.

Joe Johnston will return to direct Jurassic Park 4, written by The Departed screenwriter William Monahan. Johnston helmed the third installment of the franchise.

In September, Spielberg told the press that he would be willing to take helm of the project if Johnston didn't sign on. This move guarantees that Spielberg won't return the Lost World.

"Joe is my go-to ‘Jurassic’ guy now," Spielberg told SF in July. "I think Joe did an amazing job putting together those battles. And I think those battles Joe put together… I was jealous of the spinosaurus attack on the airplane! That scene where the spinosaurus attacks the airplane and the passengers inside the airplane was every bit as good as I thought the main road attack in ‘Jurassic Park’ was. So I’m a huge fan of Joe’s, and he’s the right guy to do the fourth one."

Jurassic Park 4 is tentatively set for a Summer 2008 release.
