## Spoilers
### Plot
The story unfolds over a single night. Sergeant Lo Sa (Lam Suet), a scruffy anti-triad detective, is baited into an alleyway after antagonizing young gangsters in a restaurant, is beaten, and wakes to find his service revolver gone.[3](https://china-underground.com/wp/movies/ptu/) Losing the weapon would end his career, so Sergeant Mike Ho ([Simon Yam](https://www.edgepedia.org/simon-yam)), commander of a Police Tactical Unit (PTU) on patrol, refuses to report the mishap and begins a secret search before dawn, on the principle that uniformed officers must protect one another.[2](https://www.tfai.org.tw/zh/program/movieDetail/2c968082978c955401981194ddd20108)
The lost gun becomes a key clue when the son of a gang boss is murdered, drawing the suspicion of Inspector Leigh Cheng (Ruby Wong) of the criminal investigation branch, who considers Lo a likely suspect.[2](https://www.tfai.org.tw/zh/program/movieDetail/2c968082978c955401981194ddd20108) As night deepens, PTU squads, detectives, and several triad factions circle one another through the empty streets, and the night ends in a brutal gunfight with a smuggling gang preparing to flee Hong Kong by sea at dawn.[2](https://www.tfai.org.tw/zh/program/movieDetail/2c968082978c955401981194ddd20108)
## Themes: the blue curtain
**Police solidarity.** To said he was most interested in the "blue curtain", also called the "blue wall of silence", the unwritten rule that officers do not report a colleague's errors or misconduct. In the film, upholding the law is secondary to saving a fellow officer's reputation, and Ho's unit breaks numerous laws and commits multiple crimes to spare Lo disgrace.[7](https://fictionmachine.com/2015/07/18/anyone-wearing-a-uniform-is-one-of-our-own-ptu-2003/) Asked whether the police really behave this way, To replied: "I don't want to say. Things happen in life. It is not a creation of my movie. If you read the paper or watch the news, you know what goes on."[7](https://fictionmachine.com/2015/07/18/anyone-wearing-a-uniform-is-one-of-our-own-ptu-2003/)
The film draws police and triads as near-mirror images. Lo and the gang leader Ponytail first meet in the same restaurant, and each man's first act is to force the other out of the same table, a duplication that suggests the two groups are symbiotic rather than opposed.[7](https://fictionmachine.com/2015/07/18/anyone-wearing-a-uniform-is-one-of-our-own-ptu-2003/)
## Production
To announced the project in 2001 but had to wait for a run of commercial hits before securing financing.[5](https://www.screendaily.com/ptu/4012568.article) Shooting stretched over roughly two years in intermittent night sessions, and To has called the film an "experimental exercise" for himself.[7](https://fictionmachine.com/2015/07/18/anyone-wearing-a-uniform-is-one-of-our-own-ptu-2003/) • [2](https://www.tfai.org.tw/zh/program/movieDetail/2c968082978c955401981194ddd20108) It was one of his semi-improvised productions: the premise was fixed early, but the cast discovered the story scene by scene as shooting proceeded.[7](https://fictionmachine.com/2015/07/18/anyone-wearing-a-uniform-is-one-of-our-own-ptu-2003/)
To shot the film entirely at night, saying "I control the lighting. In the daytime, God controls the lighting," and based his lighting on Chinese paintings, which focus on an object while leaving backgrounds hazy.[8](https://www.sfchronicle.com/movies/article/DVD-review-PTU-3197663.php) Most scenes were filmed on location in [Kowloon City](https://www.edgepedia.org/kowloon-city), Mongkok, and Tsim Sha Tsui, where the story is set; the alleyway where Lo loses his gun was filmed in Central and the climax in Ap Lei Chau.[7](https://fictionmachine.com/2015/07/18/anyone-wearing-a-uniform-is-one-of-our-own-ptu-2003/) Cinematographer Cheng Siu-keung shot the film in anamorphic widescreen with a 2.35:1 aspect ratio.[9](https://rsuir-library.rsu.ac.th/bitstream/123456789/3146/1/LIYING%20QIAO.pdf)
## Style and reception
Critics consistently describe PTU as a film of style over dialogue. The International Film Festival Rotterdam program noted that, like Hitchcock's treatment of the gun as a [MacGuffin](https://www.edgepedia.org/macguffin), the missing revolver is mainly an excuse for a flashy picture of Hong Kong's seamy side, with sparse dialogue delivered by To's regular ensemble.[6](https://iffr.com/en/iffr/2007/films/ptu) The South China Morning Post later called PTU a turning point in To's career, marking his move from off-the-cuff action films to slick, cinematic stories with production values comparable to American films, citing Yau Nai-hoi's watertight script, Cheng's wide-angle cinematography, and an eerie score mixing hisses, white noise, and guitar rock.[10](https://www.scmp.com/lifestyle/entertainment/article/3254632/stunning-action-hollywood-production-values-how-johnnie-tos-ptu-and-breaking-news-changed-game-hong?module=series_article_list&pgtype=series) On Rotten Tomatoes the film holds a 68% Tomatometer from 19 reviews and an 80% audience score.[11](https://www.rottentomatoes.com/m/ptu)
Scholars have placed the film within Hong Kong film noir. Michael Ingham, a scholar of Hong Kong cinema, defines PTU as "Tsim Sha Tsui Noir", reading the district, Kowloon's main cultural and commercial area, as a dark, depopulated, perilous city space.[12](https://eprints.soton.ac.uk/469165/1/PhD_Thesis_Yushi_Hou.pdf) The film is considered a key text of the Milkyway Image house style, which strips To's crime cinema down to movement, loyalty, and space.[13](https://cinemaanthology.com/movie-night/hong-kong/films/ptu/)
## Release and the SARS coincidence
PTU opened in Hong Kong on 17 April 2003, at the height of the SARS epidemic, which had emptied the city's streets and crippled cinema attendance.[3](https://china-underground.com/wp/movies/ptu/) • [7](https://fictionmachine.com/2015/07/18/anyone-wearing-a-uniform-is-one-of-our-own-ptu-2003/) The film's deliberately deserted Kowloon, a stylistic choice made when shooting began in 2001, coincidentally mirrored the quarantined city outside, giving the release an unintended resonance. It grossed a disappointing HK$3 million, about US$385,000.[7](https://fictionmachine.com/2015/07/18/anyone-wearing-a-uniform-is-one-of-our-own-ptu-2003/)
## Awards and legacy
At the 40th Golden Horse Awards in 2003 the film won Best Original Screenplay for Yau Nai-hoi and Au Kin-yee, and at the 23rd Hong Kong Film Awards in 2004 To won Best Director; the film also received Best Director and Film of Merit from the Hong Kong Film Critics Society and swept six categories at the 2004 Golden Bauhinia Awards, including Best Picture.[2](https://www.tfai.org.tw/zh/program/movieDetail/2c968082978c955401981194ddd20108) • [1](https://www.piecsmakow.pl/vod-film.s?id=1123&lang=en)
The film's home-video success led Milkyway Image to produce five direct-to-DVD Tactical Unit spin-off films between 2008 and 2009, supervised by Law Wing-Cheong, Lawrence Ah Mon, and Andy Ng, with Simon Yam, Maggie Shiu, and Lam Suet returning in new roles.[7](https://fictionmachine.com/2015/07/18/anyone-wearing-a-uniform-is-one-of-our-own-ptu-2003/) A 4K restoration returned the film to theaters in September 2025, with half the profits donated to To's Fresh Wave young-filmmaker program.[14](https://www.hk01.com/%E9%9B%BB%E5%BD%B1/60270014/ptu-4k%E4%BF%AE%E5%BE%A9%E7%B6%93%E5%85%B8%E9%87%8D%E7%8F%BE%E5%A4%A7%E9%8A%80%E5%B9%95-50-%E5%88%A9%E6%BD%A4%E6%8D%90%E8%B4%88%E6%9D%9C%E7%90%AA%E5%B3%AF%E5%B0%8E%E6%BC%94%E9%AE%AE%E6%B5%AA%E6%BD%AE%E8%A8%88%E5%8A%83)
