It looks like the wait between Indy 4 and Indy 5 won't be as long as between Indys 3 and 4, if what Harrison Ford has told MTV is anything to go by.
"I don't think I'll do it in a wheelchair," he says. "George [Lucas] is working on an idea, and if it comes to a fruitful stage, all of us are very interested in making another."
He goes on to promise that the film is based around an outrageous concept: "Some of the best ideas are crazy ideas, you know? Well-wrought, well-manipulated. I think it would be interesting to advance the understanding of the character, as we always have had that ambition throughout the series. I think it would be interesting to deepen the relationship between he and his son [Mutt, played by Shia LaBeouf] and play on that relationship. It's full of opportunity. The series is full of opportunity."
