George Lucas has promised that the latest installment in the Indiana Jones series will concentrate on the script rather than action stunts.

The director believes that action sequences are becoming boring and predictable in movies, and has vowed to make the dialogue in the new film the main attraction.

He told MTV: "I think Tom Cruise proved that people are getting bored with that kind of stuff. What they want to see is something different. And Indiana Jones, if nothing else, is always different.

"I think it'll be a great film, but it's completely different. It's still got a lot of action, and it's still very funny. I think it works like crazy."
