George Lucas has talked down the latest installment in the Indiana Jones series, claiming it will not meet expectations.

The producer believes the hype surrounding the upcoming movie is too much to live up to, and a lot of people will be disappointed.

He told Empire magazine: "We're basically going to do The Phantom Menace. People's expectations are way higher than you can deliver. You could just get killed for the whole thing. We would do it for fun and just take the hit with the critics and the fans."

The fourth Indiana Jones film is expected to be released in summer 2008.
