Creative background:

Infernal Affairs was inspired by the film Face to Face directed by John Woo. Siu Fai Mak thinks that "changing face" in FACE/OFF is impossible in reality, so Siu Fai Mak asks if it is possible to tell a story and exchange the two roles, but it doesn't need surgery, just the exchange of identity and heart.

When He Zhuang wrote the script of Infernal Affairs, he kept writing letters. Siu Fai Mak wrote a complete script and gave it to Zhuang. Zhuang revised the script and wrote a letter to modify it.

In Siu Fai Mak's script design, at first only the police noticed the story of the underworld undercover. Later, Liu Weiqiang added many elements to the original script, and people who joined the underworld went to the police station to do another undercover job.

In the process of revising the script, the orientation of Infernal Affairs has also changed. At first, the movie script was dominated by police and bandits fighting, but later the elements of gangster or hero films became stronger? .
