'Pirates Of The Caribbean' scribe to pen Robert Downey Jr's 'Yucatan'

'Pirates Of The Caribbean' scribe Terry Rossio has been signed to pen Robert Downey Jr.'s upcoming film 'Yucatan.'

The Warner Bros. and Team Downey project, which is based on 1700-page treatment written by iconic actor Steve McQueen in the late 1960's, Deadline.com reported.

McQueen's detailed template for the movie was found in two leather-bound trunks after his death., and thought the updated plot is under wraps, the Oscar nominated scribe and Downey Jr. are using the original premise as a jumping-off point for a mind-bending adventure story.

In a statement Downey said that Rossio was "perfect fit to embrace the existential nature of the project with the action, story and characters that drive Yucatan."

Susan Downey would be producing with RDJ and David Gambino, along with Dan Lin from Lin Pictures.
