After his short film based on the video game Portal went viral, director Dan Trachtenberg has been attached to several projects including Crime of the Century and Y: The Last Man.  Nothing has come to fruition yet, so Valencia is poised to be Trachtenberg's feature directorial debut after closing a deal with Bad Robot and Insurge Pictures (a Paramount division for low-budget projects).  The Wrap provides the synopsis for the Dan Casey script:

"The majority of the movie takes place in an underground cellar, home to a teenage girl and a caretaker.  The girl woke up in the cellar after a car accident, at which point her eerie companion tells her a nuclear attack has devastated society.  The girl still hopes to escape."

Paramount greenlit the $5 million production for a fall start date.  Check out Trachtenberg's Portal: No Escape after the jump.
