As most know, the "fourth movie" was originally a rumor from a member of a well-known Pokemon Bulletin Board. He stated that Matasamoto Rica (voice of Satoshi, for Japanese original) was interviewed, and the transcript was posted on TV-Tokyo. Supposibly, she said she was going to quit in the fourth and final Pokemon Movie. The "interview" also stated that the fourth movie would have Satoshi (Ash) opening up the "GS Ball" and releasing the "secret and most rare Pokemon"; Serebii. Of course, people who read the rumor posted on the Bulletin Boards who could read Japanese went to Tv-Tokyo's website. No such interview existed there. The whole fourth movie info was classified as "false", and a rumor. At that time, it was false. There *was* no fourth movie planned. However, before it was classified as false, other people found the rumor and posted it on their site. It spread like wildfire. Eventually, it ended up on some offical sites. Other offical sites posted it. It then got to the Sun Times even! But now, a short small clip/preview was shown at the end of "Emperor of the Crystal Tower" (third Pokemon Movie). It released that Serebii would be in it . It is terribly ironich how this could come true. But, on the other hand, it isn't. There was a high chance that Serebii would be in a movie. I mean, it is the new Mew, if you will, of Pokemon GS. Of course their going to make a movie of it.
