Nope, that is one movie that will never get made!

No Redemption for ‘Indy 4’ Writer
The latest effort to bring back Indiana Jones appears doomed, according to writer-director Frank Darabont (The Shawshank Redemption).
Darabont told a movie website that focuses on films in development that although Steven Spielberg had praised his script for Indiana Jones 4 as “the best draft of anything since Raiders of the Lost Ark, ” his excitement was not shared by fellow producer George Lucas.
In the interview with Devin Faraci of CHUD.com, Darabont said Spielberg’s praise “gave me a real sense of accomplishment, especially when you love the material you’re working on as much as I love the Indiana Jones films. And then you have George Lucas read it and say, ‘Yeah, I don’t think so, I don’t like it.’ And then he resets it to zero.”
Asked whether he believes Indy 4 will ever be filmed, Darabont replied, “I don’t think so. … I just think it’s fantastically bizarre that for a project that people have been trying to crack for ten years and have a writer come in and finally crack it and then … [for Lucas to] say, ‘No, I don’t think so…’ It’s just bizarre to me. I can’t get into George’s head.”
