Are there two もっと見る 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 スプリット, 分割 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 秒 part comes out on July 15, 2011. I believe that the cast would finish filming these 映画 次 April. I can't wait to see them! :)
