During a routine military exercise, modern-day soldiers led by Second Lieutenant Iba (Chiba) find themselves transported back in time four hundred years to war-torn feudal Japan. Facing attack by samurai warriors from rival clans, frictions rapidly emerge among these modern-day soldiers, whisked from a time of peace, freed from the structures of a higher authority and stranded in one of the bloodiest and most decisive periods in Japan's history. (From Arrow’s official synopsis)

One fun thing about exploring subgenres is that you sometimes run into one that is both unusually specific and unusually popular, like Samurai Time Travel. In J. Larry Carroll’s Ghost Warrior (1986), a samurai is frozen in ice for 400 years and awakes in modern-day Los Angeles. In Stuart Gillard’s Teenage Mutant Ninja Turtles III (1993), the titular heroes are thrown back in time to feudal Japan via an enchanted lamp. In Takashi Miike’s Izo (2004), Izo Okada (a real historical figure) battles his way through different time periods in the afterlife. Most recently, in Jun'ichi Yasuda’s A Samurai in Time (2023), an Edo-era samurai finds himself in a contemporary film studio and becomes an actor. And this isn’t even going into comics and animated series, like Samurai Jack (2001-’04, 2017) and Gunjō Senki (2017).

One of the earliest (if not the earliest) feature versions of this trope, Kōsei Saitō’s G.I. Samurai (Japanese: Sengoku jieitai; aka: Time Slip, 1979) was based on the novel Sengoku Jieitai (pub. 1975) by Ryō Hanmura, an author known for his popular historical science fiction, including The Secret History of Mt. Musubi (Japanese: Musubi no Yama Hiroku, pub: 1973) and Legend of an Enchanted Planet series (Japanese: Yōseiden, pub: 1975-95). 

This adaptation is built around star Shinichi ‘Sonny’ Chiba. Chiba’s cross genre appeal makes him a perfect candidate for a mash-up of this type, even if he was mostly remembered for his contemporary action and gangster at the time. The stage was set with a couple of war movies under his belt and samurai parts in Kinji Fukasaku’s The Fall of Ako Castle (Japanese: Akô-jô danzetsu) and the Yagyu Clan Conspiracy (Japanese: Yagyû ichizoku no inbô) TV series, both of which were released the year before G.I. Samurai. Chiba’s character arc is a bit nonsensical, but his performance is the exact kind of macho pathos the film requires.

Saitō’s direction isn’t outstanding, but he does an effective job wrangling the large cast, conveying scope, and his larger-scale action and stunts are well-orchestrated. The overall pacing, however, leaves a lot to be desired. This is mostly a case of there being a book’s worth of plot and characters. Within and of themselves, specific sequences move along just fine and I don’t think deleting little asides, like flashbacks (flashforwards?) to civilian life and soldiers making friends with the locals, is necessary. What is necessary is a clear sense of its endgame. As is, the episodic storytelling feels listless, like a series of mini-climaxes detached from the whole. It’s ambitious, but messy.

In 2005, the novel was readapted to manga by Harutoshi Fukui and as a live-action film by Masaaki Tezuka as Samurai Commando: Mission 1549 (Japanese: Sengoku jieitai 1549). It was remade again the next year as a four-part miniseries, which sounds to me like a preferable structure in which to tell the story.

Video

G.I. Samurai was released in North America and Europe under the title Time Slip (sometimes Time Slip: The Day of the Apocalypse). It doesn’t appear to have made it to stateside VHS, but there were anamorphic DVDs from defunct labels Adness and BCI Eclipse. It was later included in a Mill Creek Sonny Chiba collection. The first Blu-ray came from Japanese label-holder Kadokawa in 2012 and French company Carlotta Films also released the first 4K UHD in 2024 (alongside a Blu-ray). Arrow’s press release claims that their Blu-ray features a new 4K restoration from Kadokawa, but I don’t know if it is the same one used for the Carlotta release.

The 1080p, 2.35:1 transfer is crisp with really nice color separation, despite how much of the film takes place in dark and/or misty locations. Dynamic range and clarity is boosted by clean, if ever so slightly milky black levels. There’s plenty of texture and busy patterns throughout, though the finest texture, such as grain and close-up detail, tend to be a little soft, probably an effect of minor compression from the original 4K. Note that there is some static grain built into the matte paintings and some wide shots are particularly wobbly. Neither of these seem to be a transfer issue.

This disc includes the alternate English language version of the film under the title Time Slip. I believe the only difference is the dub and the titles, because the runtimes are identical.

Audio

The G.I. Samurai cut comes loaded with Japanese 1.0 mono LPCM, 4.0 DTS-HD Master Audio, and a 5.1 remix, also in DTS-HD Master Audio, as well as an English LPCM 2.0 to go with the Time Slip cut. The 4.0’s stereo effects are pretty tidy, though some of the effects work can be loud in a way that slightly drowns out the dialogue. Otherwise, it has a more natural sound than the 5.1 mix, leading me to guess that there was possibly a 4-track mix created for the original theatrical release. IMDb was not helpful in this regard. Either way, I stuck mostly to the mono mixes, which were very comparable in volume and clarity, in spite of the language differences (for the record, the English dub is slightly above average).

Naturally, Kentaro Haneda’s mirthful, genre-spanning score and the hippie-fied rock/pop inserts from Joe Yamanaka and Toru Matsumura sound best with stereo enhancements, but also aren’t too tinny when cramped down to mono, either.

Extras

• Commentary with Samm Deighan and Tom Mes (Japanese cut) – The authors of Revolution in 35mm: Political Violence and Resistance in Cinema from the Arthouse to the Grindhouse, 1960–1990 (PM Press, 2024) and Agitator: The Cinema of Takashi Miike (FAB Press, 2004) explore pertinent Japanese history, production challenges, the wider careers of the cast & crew, similar films (Deighan mentions The Final Countdown, for instance), narrative themes, and other adaptations of Hanmura’s book.

• The Good Fight (22:15, HD) – Art, Cult and Commerce: Japanese Cinema Since 2000 (Awai Books, 2023) author Mark Schilling discusses Saitō’s own comparisons to the coming-of-age nostalgia of George Lucas’ American Graffiti (1973), outdated/dangerous horse stunts, the true history of the Sengoku period, Japanese studios fighting the influence of TV and Hollywood, and the careers of key cast & crew members.

• Acting in Self Defense (18:05, HD) – Pure Invention: How Japan's Pop Culture Conquered the World (Crown, 2020) author Matt Alt talks about Japan’s big economic boom of the era, how that drove nostalgic sentiment, the ongoing role of the Japanese Self-Defense Forces, and the film’s production.

• Back in Time (25:47, HD) – While offering his own perspective on the film, Tatsuya Masuto sort of interviews fellow author/critic Masaaki Nomura about his time working with Kadokawa Films, including his own, on-set experiences with G.I. Samurai. They also bring up the American Graffiti comparison, which I find fascinating.
