Evangelion: 1.0 You Are (Not) Alone. (Japanese: ヱヴァンゲリヲン新劇場版: 序, Hepburn: Evangerion Shin Gekijōban: Jo, lit. "Evangelion New Theatrical Edition: Prelude") is a 2007 Japanese animated science fiction action film, written and chiefly directed by Hideaki Anno. It is the first installment of the Rebuild of Evangelion tetralogy, based on the anime television series Neon Genesis Evangelion. The story, which is set in the futuristic city of Tokyo-3 fifteen years after a planetary catastrophe known as the Second Impact, focuses on Shinji Ikari, a boy who is recruited by the special agency Nerv to pilot a giant mecha known as an Eva unit and fight, along with fellow pilot Rei Ayanami, against a mysterious species named Angels. The film features the same cast of voice actors from the original series, including Megumi Ogata as Shinji, Megumi Hayashibara as Rei, and Kotono Mitsuishi as Misato Katsuragi.

Evangelion: 1.0 was planned to be the first installment of a three-part remake of Neon Genesis Evangelion with about one hundred fifty new cuts; during the production, however, the staff could not reuse the original drawings from the series and had to begin production from scratch. As production went on, the project began to deviate from the original series, introducing differences in the plot and characterization of the characters. Hideaki Anno was joined in the direction by Kazuya Tsurumaki and Masayuki, both of whom were assistant directors of the original series. The storyboards were handled by Shinji Higuchi and Tomoki Kyoda.

The film, which retraces the plot of the first six episodes of the series, enjoyed a positive reception in Japan, grossing about ¥2 billion and generating considerable revenue for the home video market. Abroad, Evangelion: 1.0 received a more polarized reception, although generally positive; critics described it as too derivative of the classic series and claimed that it cut important details, while others praised its direction, soundtrack, and plot, with particular attention to its use of CGI graphics. The feature film also won accolades, receiving awards at, among others, the Animation Kobe and Tokyo International Anime Fair.
