Screenwriter Blames George Lucas for 'Indiana Jones' Delay
Screenwriter Frank Darabont has blasted George Lucas for the delays behind the fourth Indiana Jones movie. The highly anticipated sequel was ready for filming back in 2004, but despite a script from Darabont that impressed director Steven Spielberg, the film's producer Lucas blocked the impending shoot - citing problems with the screenplay.
Speaking to Moviehole.net, director Frank Darabont says, "That was terrifically frustrating. I worked for over a year on that. I worked very close with Steven Spielberg. He was ecstatic with the result and was ready to shoot it two years ago. He was very, very happy with the script and said it was the best draft of anything since Raiders Of The Lost Ark.
"Lucas read it and said, 'Yeah, I don't think so, I don't like it.' And then he resets it to zero when Spielberg is ready to shoot it that coming year, (which) is a real kick to the nuts. You can only waste so much time and so many years of your life on experiences like that, you can only get so emotionally invested and have the rug pulled out from under you before you say enough of that."
