Pokémon: Lucario and the Mystery of Mew (ミュウと波導の勇者　ルカリオ, Gekijōban Poketto Monsutā Adobansu Jenerēshon Myū to Hadō no Yūsha Rukario?, lit. Pocket Monsters Advanced Generation the Movie: Mew and the Wave Guiding Hero: Lucario) is the eighth Pokémon movie. It was released in theaters in Japan on July 16, 2005, followed by the Japanese DVD release on December 22, 2005. The English dub made its worldwide DVD debut in Australia on August 16, 2006, with the US release following on September 19, 2006 by VIZ Media. The English dub of the movie premiered in the US for the first time at the 2006 Comic-Con in San Diego, California. The movie aired in the United Kingdom in July 2007. While the Australian DVD has only one disc with slideshows as the sole extras, the North American DVD set comes with the redubbed The Mastermind of Mirage Pokémon special included on the 2nd disc as a bonus feature, as well as a 'Making Of' feature on the first disc along with sketches similar to the slideshows on the Australian DVD. However the Australian DVD has a widescreen presentation while the American release does not. This is also the last film to have been dubbed in English by 4Kids Entertainment, with the original cast. The background for this movie was based on visits by Kunihiko Yuyama to Bavaria, Germany. Neuschwanstein Castle and Linderhof Palace were used as the basis of the movie's setting.

"Hajimari no Uta", the ending theme for the Japanese version of the movie, is performed by Puffy AmiYumi. The ending theme for the English dub was "We Will Meet Again" performed by John Siegler.
