Plot

Yukio Daitokuji, a young doctor who has taken over his father's medical practice in Tokyo, lives with his parents and his beautiful wife Rin, who lost her memory in a fire before she met him.⁴^•⁵ After his father (Yasutaka Tsutsui) and mother (Shiho Fujimura) die in quick succession, Yukio senses a gaze following him, and one day in his garden he is attacked by a man with his own face: Sutekichi, a twin abandoned at birth because of a strange birthmark on his foot and raised in a slum.¹^•⁴^•⁶ Sutekichi throws Yukio down an old well and takes over his life, and his encounter with Rin eventually reveals her forgotten past; Yukio escapes to confront him.²^•⁴

Production

The project began at the initiative of lead actor Masahiro Motoki, who thought Tsukamoto would suit the material and wanted to work with him; Tsukamoto, a fan of Ranpo since boyhood, agreed and rewrote the short story substantially, moving the setting to the end of the Meiji period.⁷^•¹ The film was originally planned as a mid-length independent work of roughly 45 minutes to an hour, but Toho came on board and asked that it be expanded into a feature without increasing the budget, making Gemini one of Tsukamoto's rare studio pictures.⁷ It was produced by Sedic International with Marubeni, with Tsukamoto's own company Kaijyu Theater cooperating fully, a combined major-studio and independent structure.¹

It was Tsukamoto's first period film, after futuristic and contemporary settings in earlier work such as Tetsuo: The Iron Man (1989), and his first feature he did not originally devise himself.⁷^•³ Unlike the monochrome or near-monochrome look of much of his earlier work, the film is shot in vivid color, and the cast had their eyebrows shaved off and received distinctive makeup to create an eerie, grotesque mood.⁶^•⁴ The costumes were by Michiko Kitamura, whom Tsukamoto admired.¹

Themes and style

The film treats class division in Meiji Japan, contrasting the doctor's status and honor with the slum-raised twin, and turns on psychological doubling, amnesia, and revenge.⁸ Tsukamoto's official site identifies the "adversarial double" as one of his important motifs.¹ Critics noted the application of his kinetic visual style to a costume drama; the Rotterdam festival program called it "Hammer Gothic on acid" with full-blooded performances, and the Toronto International Film Festival guide described almost Gothic compositions, much silence, and strict attention to classical costume and music.⁸^•⁹ Reviewers have also drawn comparisons to David Cronenberg's Dead Ringers, another story of doubled identities.¹⁰

Reception

Gemini was screened in competition at the 56th Venice International Film Festival and at the Montreal International Film Festival.⁵ It won the audience award at the 1999 Busan International Film Festival, the Grand Prix at the 2000 Neuchâtel festival, the music award at the 2000 Sitges festival, and best actress at the 14th Takasaki Film Festival for Ryō.¹ On Rotten Tomatoes the film holds a 100% Tomatometer from five professional reviews and a 70% Popcornmeter from more than 500 audience ratings; IMDb users give it 6.7 out of 10.²^•¹¹ Later critics read it as a melodrama of the haves and the have-nots, of nature and nurture, and as a film that stood apart from the contemporary J-horror wave through a more extreme approach.²
