Undoubtably the best Hong Kong film I’ve watched in a long time, Infernal Affairs sees veteran actors Andy Lau and Tony Leung square off as opposite undercover agents both in the police and drug syndicate. Wasting little time in establishing the plotline seeing the both of them embarking on their incognito missions, the story jumps forward to the present day with each of them working ever more feverishly as they try to take each other out before any of their true identity is exposed. The battle that rages on is two-fold; the physical, tangible need to remain undiscovered while remaining useful to their original cause, and the internal, psychic wrestle to remain true to their identity and shrug off the embattled weariness. In the end, no one escapes unscathed and the victory that is claimed is not without a sinister twist of irony. I especially enjoyed the conundrum exchange of words and battle of wits between the two protanganist excellently played by Andy Lau and Tony Leung. A masterful piece not to be missed.
