Is there another final fantasy 7 movie besides advent children?

Yes. There is Final Fantasy Last Order. It is not actually a movie-since it's only around 26 minutes in length. And it only shows some of the events happening after Crisis Core. You know, Cloud and Zack escape the Shinra Inc. and Zack fights to protect Cloud and later on dies in the struggle (part which I hated most..why the hell did Zack have to die??) and also the fight between Zack, Cloud and Sephiroth in the Nibleheim reactor, after Sephiroth burned the village. That's pretty much it! But rumors are that Square Enix is going to make a remake of Final Fantasy 7 (movie and game..OH YEAH!!).
