Hot off the $600m-plus global success of Fast Five, Walker will star as a father desperate to keep his newborn alive in post-Katrina New Orleans.

Eric Heisserer, who write Universal’s upcoming sci-fi release The Thing as well as Final Destination 5 and A Nightmare On Elm Street remake, wrote the screenplay and will make his feature directorial debut.

Peter Safran will produce though Safran Company, and is also financing the project. Production is being lined up in and around New Orleans for March 2012.

UTA Independent Film Group packaged the project with Safran. UTA and manager Matt Luber of Luber Roklin represent Walker and the agency also represents Heisserer alongside manager Julie Bloom of Artwork Entertainment.

Hours marks the second Walker project produced by the Safran Company, which just wrapped principal photography on Vehicle 19

The Safran Company also produced director Rodrigo Cortes’ Buried, which UTA sold to Lionsgate at Sundance 2010, and this year’s Sundance entry Flypaper starring Patrick Dempsey, which sold to IFC.
