In a recent interview with Comingsoon.net, veteran producer Frank Marshall responded to a number of questions regarding fourth installments of his popular series, including Jason Bourne, Indiana Jones, and Jurassic Park. On the latest dinosaur adventure, Marshall said that while the current WGA strike is holding up script revisions, the film is still on track for a 2009 release. “There’s an idea and we just have to see if it shakes out,” he said. While it’s disappointing to hear that the script has yet to be finalized, the fact that Frank Marshall still considers the project to be greenlit should be somewhat reassuring to long-starved fans.
