According to its Japanese movie website, another Pokémon movie is on the way. By summer of 2011 the movie should hit, which will put this at movie number 5 million.
Maybe the number is far less than 5 million, but there has been new Pokémon movies releasing every summer since 1998. That is a whole lot of movies.
Last year’s Pokémon movie took the number 2 spot at the Japanese box office, so it was obviously a no-brainer to release another. The upcoming film is said to tie into the current anime series, Pokémon: Best Wishes! Pokémon is not only a long-lasting series of games, but the anime is a beast all on its own.
