Oscar-winning actress Cate Blanchett is in talks to star opposite Harrison Ford in the long-awaited return of Indiana Jones, her publicist has confirmed.

"She is in negotiations, yes," publicist Lisa Kasteler told the AP news agency.
Shooting is due to begin in June with the movie expected to open in May 2008.
The original Indiana Jones trilogy was a tribute to Saturday morning B-movies, and made more than $1.1bn at the box office in the 1980s.
The fourth instalment was in development for more than 10 years before creator George Lucas and director Steven Spielberg finally signed off the script.
Earlier in the year, Lucas said it would be "a character piece" including some "very interesting mysteries".
The screenplay was written by Jurassic Park and War of The Worlds scribe David Koepp, who told film website IGN it had taken "about a year" to complete.
Harrison Ford, who last played the Jones role in 1989, is now 64.
Last year he said he would "bring the same physical action" to the new film as he did to the original trilogy.
Blanchett, who won a best supporting actress Oscar in 2004 for The Aviator, most recently starred in Notes on a Scandal and Babel.
