Internal Affairs III is the final film in the trilogy, this film is like the prequel (the second installment) directed by Andrew Lau and Alan Mak, the former being the one who directed the original. This third film serves as both a prequel and sequel to the first film, as it continues after the events of the first film and before those events. Andy Lau and Tony Leung reprise their roles from the first film as Senior Inspector Lau Kin-Ming, an ex-Triad spy in the Hong Kong Police Force who tries to cover his criminal past and remain as a cop. Tony Leung as Chan Wing-Yan, an undercover Hong Kong Police Force officer in the Triad. He was killed by Inspector B in the first film, but returns in the prequel aspect of the film. Kelly Chen, Anthony Wong, Eric Tsang and Chapman To also reprise their roles again, joined by new cast members Leon Lai and Chen Daoming. Andy Lau actually won the award for Best Actor in the Golden Horse Awards, well deserved I must say. The film was nominated for a lot of other different awards. Andy Lau's acting is superb. Being one of the new cast members, I think Leon Lai is one of those standout performances in the film as Superintendent Yeung Kam-Wing who's Lau's rival in the police force. Chen Daoming is too quite great as "Shadow" Shen Cheng, two good additions to the trilogy.
Months after the events of the original film, Ming suspects a police superintendent as being a new mole for the triads, while years earlier, Yan embarks on his first mission.
So I bought the whole trilogy on Criterion and I got the director's cut of the movie, more than I knew before buying as I had only heard about the first film. I thought this version of the film was a good viewing, a crime story worth telling, with great themes. Will Lau survive the infernal agonies of fear, paranoia, and lack of trust? Watch and you'll find out. It contains many satisfying answers to questions that have lingered after the first two installments. I've seen the question is it unnecessary? It depends on how much you like the story and characters, I don't think this film was wanted, but it was needed and it's because of the story and how much depth it has. The questions you might have, are answered here. The first film ended perfectly and the second installment was a great prequel that gave more context and just more, this film struggles but ends up being a fine addition. Also a satisfying conclusion to the trilogy, I think the pacing could have been better and some of the writing too. Yet, it's solid, tying up loose ends and brings the character arcs to a satisfying conclusion. Especially Lau's character arc. I think the ending was fitting. The trilogy could have worked as one film, but how the writers and directors expanded the story and characters, into something memorable. This was a terrific trilogy. Internal Affairs III was a good crime drama, perhaps a bit unnecessary, but good.
