Television creator/producer/writer Josh Schwartz (The O.C., Chuck, and Gossip Girl) will make his feature directorial debut with the Halloween comedy Fun Size.  Penned by Colbert Report writer Max Werner, Fun Size tells the story of a girl who is forced to take her little brother trick-r-treating and accidentally loses him along the way.  Based on that one-line premise alone, I'm getting an Adventures in Babysitting/Don't Tell Mom the Babysitter's Dead meets Halloween vibe.  A vibe I'm completely okay with, I might add.

Per THR, Schwartz (who also has a writing credit on the upcoming X-Men: First Class) will develop Fun Size under his Fake Empire moniker for Paramount.  The hope is to have the film shooting in St. Louis by late spring and in theaters by Halloween 2011.  With that type of turnaround in mind, we should be hearing casting news for the film in the very near future.
