Pokémon 3: The Movie is a 2000 Japanese anime film directed by Kunihiko Yuyama as the third film in the Pokémon franchise. The film stars the voices of Rica Matsumoto, Ikue Ōtani, Mayumi Iizuka, Yūji Ueda, Koichi Yamadera, Megumi Hayashibara, Shin-ichiro Miki, Ai Kato, Masami Toyoshima, Akiko Yajima, and Naoto Takenaka. In the film, Ash and his friends go on a journey to save Molly from an illusionary pokemon named Entei.

Like its predecessors, it is preceded by a short film, this one titled Pikachu & Pichu, which marks the debut of the mischievous Pichu Bros., who help Pikachu reunite with his trainer after being separated (without Ash even knowing, due to him preparing a party to celebrate the day Pikachu and he first met). This was also the first Pokémon film to premiere in an IMAX theater. The realistic crystallization and Unown created a 3D effect in the film. This was also the last Pokémon film to be released internationally by Warner Bros. until the release of Pokémon: Detective Pikachu in 2019. The Japanese opening theme is OK! 2000 by Rica Matsumoto, and the Japanese ending theme is The Day a Rainbow Was Born (Niji ga Umareta hi) by Kumiko Mori. The English opening theme is Pokemon Johto by PJ Lequerica, and the English ending theme is To Know the Unknown by Innosense.
