Story

The plot is an original story rather than an adaptation of any single game.⁹ Layton receives a letter with enclosed opera tickets from Janice Quatlane, a former student who is now an opera singer. She reports that her friend Melina, who died a year earlier, has appeared as a seven-year-old girl claiming to have obtained eternal life.² Layton, Luke, and Emmy travel to the Crown Petone Opera House, where a new opera by composer Oswald Whistler dramatizes the legend of the lost land of Ambrosia and its secret of eternal life, a subject Layton's mentor Dr. Schrader had researched.²

The performance is a cover. The audience has gathered to seek eternal life, and when a masked man takes the stage, a puzzle game begins in which a single victor will be granted eternal life.² The story then moves through escapes, a theater that transforms into a cruise liner, and a mysterious Atlantis-like island as Layton works out the truth behind the competition.¹⁰

Production

The film adapts the Professor Layton series, a line of puzzle-solving adventure games for the Nintendo DS that had sold more than 7.3 million copies in Japan by the time of the film's release; the DVD publisher later cited roughly 9.4 million copies shipped worldwide.¹^•⁷ Level-5, the series developer, served as the original creator, with company president Akihiro Hino handling planning, producing, and the story concept.² Hikaru Tago provided puzzle production support.²

Studios and staff. Animation was produced jointly by P.A.WORKS, which also animated the games' cutscenes, and OLM, the studio behind the Pokémon films.²^•⁸ Takuzo Nagano drew the original character designs, Noboru Sugimitsu served as character designer and chief animation director, and Masafumi Mima was sound director.² The production committee, credited as Team Layton, included TBS, whose film chief Kazuya Hamana described the picture as the network's major winter release of 2009.²^•⁸

Casting. The film kept the games' voice cast: Yo Oizumi as Professor Layton and Maki Horikita as Luke, roles they had held since the first game, joined by Nana Mizuki as the opera singer Janice Quatlane, Saki Aibu as Layton's assistant Emmy (Remi in Japanese), and Atsuro Watabe as the masked scientist Jean Descole.⁵^•⁹ Mizuki, a singer as well as voice actress, also performs Janice's singing in the film.⁹

Place in the series

The film is set in the series' prequel timeline. Game Informer places it three years before the events of Professor Layton and the Diabolical Box; other coverage places it after Professor Layton and the Last Specter and before Professor Layton and the Miracle Mask.⁶^•¹¹ It was the first theatrical film for the series, which had begun with Professor Layton and the Curious Village in 2007.⁹

Level-5 announced plans to continue the Layton films as an annual event, but no sequel was made.¹⁰

Reception and release history

Japan. The film opened nationwide on Toho screens on 19 December 2009.¹ A standard-edition DVD followed from Pony Canyon on 21 July 2010, priced at 3,080 yen including tax, with a 5.1-channel Dolby Digital track and an audio commentary.⁷

Overseas. Manga Entertainment UK licensed the film in April 2010 and released it on DVD and Blu-ray that September with an English dub.¹¹ Viz Media announced North American distribution at the 2011 Anime Expo, the film's first official availability in the United States.⁶ In August 2024, Discotek Media announced an HD Blu-ray release for North America.¹²

Critical response. On Rotten Tomatoes the film holds a 77% Tomatometer from three critics and an audience score above 250 ratings.¹³ Reviewers have singled out the way the film integrates puzzle-solving into its narrative: the film critic Grant Watson, an Australian film critic who has written for outlets including SBS, called it one of the most accurate videogame adaptations ever made because puzzles are presented so the audience can work out each solution while watching.¹⁰ A 2018 Crunchyroll feature argued the film succeeds as a video game anime by telling a story suited to a film while remaining faithful to the source material's puzzle gameplay.¹⁴
