Infernal Affairs (2002): A mole in the police force. An undercover cop inside the criminal organisation. The objective is the same: each must discover the other before their own position is exposed. Who will succeed and who will pay the ultimate price for their failure?

A gripping police Hong Kong police thriller, starring Andy Lau and Tony Leung, the super-stylish Infernal Affairs was the biggest grossing Hong Kong film of 2002 and has even seen the Hollywood remake rights snapped up by Martin Scorsese.

Infernal Affairs 2 (2003): Drawing favourable critical comparisons to The Godfather - Part 2, Infernal Affairs 2 similarly explores, in prequel form, the events that took place as Lau Kin Ming (Chen) and Chen Wing Yan (Yue) infiltrated the police and criminal forces...

Infernal Affairs 3 (2003): 10 months after the murder of Chen Wing Yan (Leung), the investigation is closed with the conclusion that Ming (Lau) successfully took out the Triad's mole. Relegated to a benign office job and his marriage over, a new star enters the IA team, in the form of the up-and-coming Superintendent Yeung, whose meteoric rise mirrors that of Ming. Suspecting that Yeung is a mole like he was, Ming begins to investigate the new hot-shot...

Involving a complex flashback narrative binding the new investigation with the previous events from the first film, Infernal Affairs 3 has invited favourable comparisons with Francis Ford Coppola's classic Godfather trilogy.
