* DevelopmentHell: The American remake has been on the cards for years:
** In 1992, Creator/WalterHill and David Giler wrote a screenplay for Tri-Star Pictures that was to star Creator/RichardGere and Creator/DenzelWashington. In June of that year, it was announced that Hill and Giler were writing a script titled ''Hong Kong'' that was based on the film, with Hill directing. The producers had difficulty with the relationship between the two main characters, as they felt that American audiences would interpret it as a homoerotic one. Producer Terence Chang, who worked with Creator/JohnWoo on several productions, suggested to the American producers to have Creator/MichelleYeoh play the role of the police officer to resolve any homoerotic reading of the film. A year later, screenwriters Jim Cash and Jack Epps, Jr. were hired by producers Charles Roven and Robert Cavallo to write a screenplay based on the film for Tristar, in which they wrote a third draft dated on 23 August 1993 that featured a story of a Caucasian hitman living in Hong Kong. This screenplay moved the focus from the pairing the hitman and the police detective characters to the characters of the blinded night club singer and the hit man.
** In October 2007, ''The Hollywood Reporter'' announced that the remake was announced with Korean-American director John H. Lee directing that would take place in Los Angeles's Koreatown, Chinatown, and South Central. The film was to be produced by Woo, star Jung Woo-sung and shot in 3D. Seven Stars Film Studios was slated to finance the production with a screenplay by Josh Campbell. Sarah Li was initially cast to play the role of the blind singer. Woo spoke about the remake in October 2015, stating that it was in development for some time and Lee eventually took on other projects.
** Woo said that he planned to make the American version after his film ''Manhunt''. Creator/UniversalStudios is set to develop a script written by Eran Creevy based on drafts by Josh Campbell and Matt Stuecken. Creator/BrianHelgeland has been hired for additional writing and Creator/LupitaNyongo has been cast in the lead role. Woo said that filming would begin in January 2019. In November of that year, Woo told ''Deadline'' that Nyong'o had left the film due to another project and they have have re-written the script and it took so much time.
* ExecutiveMeddling: Tsui Hark, the film's producer, attempted this multiple times on Creator/JohnWoo as an extension of their disagreements over ''Film/ABetterTomorrow II''. Tsui Hark originally wanted nothing to do with the film, saying "[[ItWillNeverCatchOn nobody wants to see a film about a killer]]", and forced Woo to change his intended jazz song opening to a pop song, claiming that Hong Kong people didn't understand jazz. He also attempted to have the film recut to focus on Li, but Woo refused. Since he demanded this so late into post-production, Hark was not able to recut the film himself. When the film was greeted with high praise in its Taiwan premier, Hark was supposedly so livid that he trashed his own office.
* NoStuntDouble: Creator/DannyLee did most of his own stunts, as he has a black belt and karate and is a karate instructor.
* OnSetInjury: Creator/ChowYunFat was injured during the filming of the church shootout when a piece of plaster cut his face, missing his eye by an inch. You can see the cut during the part where Jeff and Li talk before leaving the church.
* OrphanedReference: When Ah Jong and Li leave the church, you can see smoke in the background. This is the result of a deleted scene where Frank throws a smoke grenade into the church.
* ProducedByCastmember:
** The movie was not able to be filmed until Creator/ChowYunFat stepped in and enlisted the company he was contracted with, Golden Princess Film, to fund part of the project.
** Creator/DannyLee was under an exclusive contract with Cinema City and was only able to work on the film if his production company, Magnum, was involved.
* SimilarlyNamedWorks:
** There is actually a 1972 Creator/ShawBrothers movie, also titled ''The Killer''. Both movies had plenty of gunplay and shootouts, but the similarities end there.
** There's also Creator/DavidFincher's ''Film/TheKiller'' (2023).
* SurprisinglyLenientCensor: The film passed British censors unscathed except for a single scene — a brief shot amid a bloody gunfight where Ah Jong stabs a bad guy in the back with a knife — because unlike guns, "people actually have knives in their kitchen".
* ThrowItIn:
** During the assassination at the boat race, Ah Jong wraps a bandana around his left hand. At the time that this scene was filmed, Creator/ChowYunFat was simultaneously working on ''Film/TigerOnBeat''. On the set of that film, he cut his finger on the front sight of a Sterling MKIV during a stunt. Afterwards, he went straight to the set of this film to shoot the assassination scene, with his hand still injured and the bandana wrapped around it. John Woo decided to include this in the film.
** The bloody injury below Chow Yun-Fat's left eye is real and was caused by a piece of plaster during the climactic shootout (see OnSetInjury above). Rather than go to the hospital, he suggested they keep filming and use it as part of the illusion.
** The film's subversion of DiedInYourArmsTonight during the ending was originally meant to be played straight, but Creator/JohnWoo was forced to improvise due to scheduling conflicts.
* WhatCouldHaveBeen: The original ending of the film involved Jennie waiting at an airport for Li to give her the money and for them to travel to the United States. Due to Sally Yeh's tight filming schedule, the scene was not filmed and replaced with Ah Jong playing the harmonica.
* WritingByTheSeatOfYourPants: Creator/JohnWoo went into filming with only a short treatment for the film and wrote the details of the script while filming.
