Indiana Jones IV

Good grief! There's going to be an Indiana Jones IV move, with Cate Blanchett and Harrison Ford....and Sean Connery.

SHE was seduced by a school student in her last flick - and it looks like the age gap won't be much different for Cate Blanchett's next potential on-screen affair.

The sultry siren, who played high school teacher Sheba Hart in Notes on a Scandal, has just signed on to star alongside ageing Harrison Ford in an upcoming addition to the Indiana Jones series.

While the specifics of Blanchett's role are being kept under wraps – along with David Koepp's screenplay – it is believed the 36-year-old beauty will feature prominently in the flick.

However, it has been revealed Ford will definitely be reprising the title role he made famous in the '80s – though at 64, and more than a quarter of a century after the original hit the big screen,  it's unsure whether he will be more convincing in the role of intrepid archaeologist or one of his fossils.

Not that he is likely to be the oldest cast member on set, with Sean Connery also linked to the project – reprising his role as Indiana's father.

Steven Spielberg will direct the flick – currently known simply as Fourth Instalment of the Indiana Jones Adventures – when it starts shooting in June, with Star Wars creator George Lucas signing on to produce.

That really does sound like one to avoid there.
