“A dark chapter that should never be forgotten…” Well Go USA has revealed a chilling first look teaser for a Chinese film titled 731, also known as Evil Unbound telling the shocking true story of the awful Japanese Unit 731 at the end of WWII in China. Yet another new film from China about how horrible the Japanese Army was – which makes me worried they’re trying to get Chinese people to hate Japanese again. Which is not okay. Set against the backdrop of the bacterial experiments conducted by the Japanese Imperial Army’s Unit 731 in Northeast China, and reveals the crimes of Unit 731 through the turbulent fate of an ordinary individual. Based on true events during WWII in Northeast China, an ordinary man is thrust into a horrible fate during the inhumane experiments conducted by the Japanese’s notorious Unit 731. Starring Wu Jiang, Zhiwen Wang, Naiwen Li, Qian Sun, and Ziye Lin. This packs in quite a bit of unsettling footage in only 15 seconds! This is a seriously effective teaser. This looks terrifying! Stay tuned for the full trailer soon.
Here’s the US teaser trailer (+ two posters) for Linshan Zhao’s thriller film 731, direct from YouTube:
The story of the Japanese Army’s Unit 731 in Harbin’s Pingfang District on the eve of victory in the War of Resistance in 1945. Under the guise of “water supply & epidemic prevention,” this nefarious unit carried out bacteriological warfare research and slaughtered civilians through human experimentation, exposing many crimes against humanity. Through the tragic ordeal of innocent civilians such as street vendor Wang Yongzhang—who were deceived, captured, imprisoned, and reduced to inhumane subjects of live experiments, the film depicts the suffering, awakening, and indomitable resistance of ordinary people in the torrent of war. 731, also with the English title Evil Unbound, and titled 731: 生化启示录 or 疯狂731 in Mandarin, is written and directed by Chinese filmmaker Linshan Zhao, director of the film The Assassins with Chow Yun-Fat previously, though not much else since then. It’s produced by Hong Wang, Zhuang Yan, and Wang Zhang. Well Go USA will release Linshan Zhao’s 731 film in select US theaters at the exact same time as it opens in China – starting on September 19th, 2025 coming soon. Anyone curious to watch this?
