Toei Animation announced at the Tokyo Anime Fair on March 23, 2006 that an animated film would be produced, and was released theatrically by Toei Company on September 15, 2007. The film is a reinterpretation of the Clannad storyline which centers on the story arc of the female lead Nagisa Furukawa. It was the final film directed by Dezaki before his death in April 2011.

A promotional campaign took to the streets of Akihabara on March 10, 2007 transported in a large black bus with the words "Film Version Clannad" (劇場版CLANNAD, Gekijō-ban Clannad) painted on the sides. A group of young women cosplaying in the female high school uniform from Clannad emerged from the bus to hand out flyers and pink and white colored thundersticks to passersby to promote the film.
