The fourth installment of the Indiana Jones film began its first day of principal photography on Monday.  This marks the first collaboration between director Steven Spielberg, actor Harrison Ford and executive producer George Lucas since Indiana Jones and the Last Crusade was released in 1989.

The film will shoot in various locations around the world throughout the summer and hit theaters on May 22, 2008.  Star Shia LaBeouf, who is rumored to be playing Indiana Jones' son though no official announcement has been made, said of seeing Harrison Ford wearing the fedora for the first time, "Oh my god, man...it's really overwhelming."
