# Forensic Heroes (franchise)

Forensic Heroes is a series of TVB police procedural television dramas written by Choi Ting-ting (I–III), Chan Ching-yee (I–II), Leung Man-wah (III-IV), Yuen Mei-fung (IV), Sin Chui-ching (IV), Yip Tin-shing (V) and Sin Siu-chun (V), and produced by Mui Siu-ching (I-IV)and Ben Fong (IV-V). The series follows a group of Hong Kong forensic scientists working together with the Hong Kong police to solve murders through physical evidence left over from crime scenes. Currently, two serials and three reboot installment were produced.
The series is said to be a contemporary version of the successful historical-fiction series Witness to a Prosecution (1999–2002), a drama that documents the life of Chinese forensic medical expert Song Ci. Forensic Heroes is also said to be loosely influenced by the American television series CSI: Crime Scene Investigation. However, unlike CSI, which uses significantly darker and bleaker lighting throughout its episodes, Forensic Heroes is presented in a brighter, more clinical atmosphere.
The series first installment, Forensic Heroes, originally ran for 25 episodes on TVB Jade from 13 June to 16 July 2006. The drama met critical acclaim and became a popular hit, with the episode finale peaking to 43 points with over 2.7 million viewers. Two years later, TVB released the subsequent sequel, Forensic Heroes II, running for 30 episodes from 19 May to 28 June 2008. Though the sequel proved successful, ratings did not break 40 points.
A reboot of the original series, Forensic Heroes III premiered on 10 October 2011, and was the most watched TVB drama of 2011. Another reboot, Forensic Heroes IV, premiered on 17 February 2020, and was the most watched TVB drama since 2013. The third reboot, Forensic Heroes V, premiered on 17 October 2022.
