Earned the Guinness World Record for most advanced ticket purchase for an animated motion picture, coming in at 2,384,198 tickets. This is the second time the Pokemon franchise has made it into the book.
In a leaked press release, the dub title for the film was revealed in August 2009 - less than a month after it was released in Japan. Normally, several months pass between the Japanese release of a Pokemon film and the revelation of the English dub title.
The actor who plays Arceus, Tom Wayland, is head of the production company that dubbed the film: DuArt. In the film, Arceus is considered the equivalent of God; thus, the casting of Wayland was a tongue-in-cheek reference.
Tom Wayland recorded several versions of his voice and had the rest of the cast choose which one would be the best for Arceus. The winner is the one heard in the film. The runner-up was a sound-alike of Charlton Heston's voice of God in The Ten Commandments (1956).
This is the Pokemon movie with the least amount of main human characters. Aside from Ash, Dawn and Brock, the only other humans with large roles are Sheena, Damos, Marcus, and Kevin. The other main characters are Pokemon, mainly Arceus.
The film premiered on Cartoon Network in November 2009, four months after it premiered in Japan. This is the first time a Pokemon film premiered internationally in the same year as it premiered in Japan.
