Spielberg says "Indiana Jones 4" was all Ford's idea

In an interview with Moviehole today, Steven Spielberg talked a little about "Indiana Jones 4". Spielberg says, the idea of a catch-up was what inspired the idea of a fourth film. “ (I thought) It would be fun to have a reunion with everybody, you know? It was really Harrison who got me into it. He was the guy that said, ‘I want to do one more,’ and he got George and I interested in working with him again, so the script’s being written, I’m going to shoot it late 2004 coming out July ’05 for the July 4 weekend,” Spielberg happily confirms.
