@lillyrox,
don't think so
from wikipedia
A two-part film adaptation of Harry Potter and the Deathly Hallows is planned, with David Yates directing both parts. Part I is slated for release on 19 November 2010, and Part II on 15 July 2011. The script was delayed as Steve Kloves did not start working on it until the 2007"2008 Writers Guild of America strike had ended. Filming began in February 2009 and ends in June 2010.
