[citation needed] Hitman in the City was planned by Neo to be an extension of his original eight-minute spoof movie, Replacement Killers, which won him the Best Director in the 1988 Singapore International Film Festival Silver Screen Awards.
[2] Also while other filmmakers used Super 8 or Super 16 cameras and convert them into standard 35mm films during post production, Jack Neo wanted to post produce Hitman in the City on VCD, VHS and Singapore Chinese television channels instead of releasing it as a film to be released in cinemas.
Other sponsors included Acer, Institute Estetica De Beaute, Seksun Precision Engineering, Great World City, Fits Clothing, National Apparel and the now-defunct Singapore branch of Au Bon Pain.
The executive chairman of Seksun was Felix Ong, who played Black Fatty in the film and assisted with production.
