Cate Blanchett has signed on to star in the fourth installment of the "Indiana Jones" adventures.
Harrison Ford already has boarded the project, which will be produced by Lucasfilm and directed by Steven Spielberg.
With David Koepp's screenplay shrouded in secrecy, it is unclear what character Blanchett will play. However, sources said the Oscar-winning actress has landed a starring role.
Shooting will begin in June in Los Angeles and at undisclosed locations around the world.
Paramount Pictures will release "Indy 4" day-and-date around the world on May 22, 2008, with a handful of territories opening the following day.
