This Guardian review covers Unidentified Murder, a low-budget Hong Kong comedy from directors Kwok Ka-Hei and Jack Lee Chun-Kit that satirises true crime enthusiasts and social media influencers. The plot centres on childhood friends Mark and Kit, who at age seven claimed to have witnessed a classmate's alien abduction, and who go viral 25 years later when the supposed anniversary reignites public interest. Their fame is exploited by Mark's girlfriend, who stages a fake reunion with a hired actor for social media clout, only for the stunt to spiral into what appears to be a real murder.

The reviewer praises the film's intricate, twist-laden structure, in which victims and perpetrators repeatedly swap roles, and its handheld camera style that lends authenticity to its depiction of online media, though this sometimes undercuts the cast's physical comedy. While the constant reversals occasionally feel like a self-conscious writing exercise, the film's ambition on a modest budget is commended, and the chemistry between lead actors Ling Man-lung and Ronald Lam is singled out as its emotional anchor. Unidentified Murder opens in UK cinemas on 11 September.
