Paramount has set "Fun Size" for an Oct. 12, 2012 release, the studio announced Tuesday.
The movie is about a troubled but whip-smart teen girl who loses her oddball little brother on Halloween, and has one desparate night to track him down.
Josh Schwartz, best known for his television work — he executive produced "Gossip Girl" and "Chuck" — directed and produced.
Max Werner wrote the screenplay. In addition to Schwartz, the movie is produced by Brad Dorros, David Kanter and Stephanie Savage.
