Paramount Pictures has set "Fun Size" for an October 12, 2012 release, the studio announced Tuesday.

The comedy is about a troubled but whip-smart teenage girl who loses her oddball little brother on Halloween, then has only one desperate night to track him down.

Josh Schwartz, best known for his television work -- he executive produced "Gossip Girl" and "Chuck" -- directed and produced.

It stars Josh Pence, Johnny Knoxville, Victoria Justice and Chelsea Handler.

Max Werner wrote the screenplay. In addition to Schwartz, the movie is produced by Brad Dorros, David Kanter and Stephanie Savage.
