At the age of 63, Harrison Ford doesn't seem to have his thoughts set on retirement just yet! It is now confirmed that he will star in a fourth Indiana Jones movie which, once again, will be directed by Steven Spielberg and produced by George Lucas. The three previous films were amongst the biggest box office hits of the '80s, starting with Raiders Of the Lost Ark in 1982, then Indiana Jones and The Temple Of Doom in '84 and culminating in the third installment, Indiana Jones and The Last Crusade in 1989. The script for the new film was approved this week, shooting is expected to start soon and the movie is scheduled to appear in cinemas in May 2007.
