Are there two more films coming out? Are the cast done filming them yet? What are they doing to name both of them?

Yes, but it's really one movie split into two: Death Hallows Part 1 and Deathly Hallows Part 2. They already finished filming most of the movie.

Yes, the first part comes out on November 19, 2009 and the second part comes out on July 15, 2011. I believe that the cast would finish filming these movies next April. I can't wait to see them! :)
