The Smurfs writers J. David Stem and David N. Weiss have already completed a script for Smurfs 2, which comes to theaters August 2, 2013.

The script was handed in a couple of weeks ago, due to the large amount of lead-time required for live action/CG hybrids.

Neil Patrick Harris, Jayma Mays, and Hank Azaria are expected to return for the sequel.

No production date has been set.
