Spielberg would give up 'Skull' writer

Rex Features

The possible success of Ghost Town may put the next Indiana Jones film at risk, Steven Spielberg has admitted.

The upcoming movie starring Ricky Gervais is written and directed by David Koepp, who penned Indiana Jones And The Kingdom Of The Crystal Skull.

Spielberg acknowledged that Koepp may not be willing to return to the Jones franchise if he thrives as a director.

However, the filmmaker said: "I want him to succeed so much that I'm willing to sacrifice the working relationship between a writer and a director to be able to capitalise on the new working relationship between DreamWorks and David as a director.

"I'm perfectly willing to give up David writing for me if he starts to consistently succeed as a director."
