Smith set to play Katrina hero

Will Smith is to play a real-life Hurricane Katrina hero in new film to be written and directed by someone named Hancock.

The 'Hancock' star will help take 'The Rookie' screenwriter John Lee Hancock's new film about ex-Marine John Keller to the big screen.

Keller helped rescue more than 200 of his New Orleans, Louisiana neighbors when they were left stranded by the devastation of Katrina in 2005.
