Air is a 2005 Japanese anime drama film directed by Osamu Dezaki and written by Makoto Nakamura based on the visual novel Air by Key. Originally, the film was set for a release date in autumn 2004, but was delayed; the film finally premiered in Japanese theaters on February 5, 2005. The film, animated by Toei Animation, is a reinterpretation of the original Air storyline which centers on the story arc of the female lead Misuzu Kamio. Yukito Kunisaki arrives in the town of Kami for a chance to earn money at the summer festival and meets Misuzu on his first day in town. They soon become best friends and a story one thousand years old begins to unfold.

Before going to DVD, a 30-minute sample of the film was streamed online by Animate from June 2–16, 2005, two weeks later. The film was later sold on DVD and released in three editions: the Collector's Edition, the Special Edition, and the Regular Edition on August 5, 2005. The Air film was licensed for English language distribution by ADV Films and was released on December 11, 2007. The license of the film was transferred to Funimation in July 2008 who will continue to release the film in North America. To commemorate the release of the Clannad film, Animate streamed the Air film on their website which was split into three parts.
