The Big Heat (城市特警) is a 1988 Hong Kong action film starring Waise Lee and Joey Wong.

Johnnie To stated that "Tsui had lots of ideas [for The Big Heat], changing the script all the time, but three days later he would come up with something totally different.

"[2] To went on to describe that the violence in the film originated from Hark's suggestions, and that it was "a very difficult project".

[1] It was described by Lisa Morton as a "minor box office disappointment", grossing HK$4.076 million and being the 94th highest-grossing film in Hong Kong in 1988.

[2] Johnnie To reflected on the film in the late 1990s, stating that "it's good at places, but it was chaotic".
