Andrew Lau and Alan Mak’s 2002 thriller Infernal Affairs screens Sunday, July 28th at Christie Pits Film Festival, as part of the summer-long Dynamic Duos series at parks across the city. It follows the story of a police officer and a member of a crime syndicate who infiltrate each other’s organizations, leading to a high stakes game of cat-and-mouse between the two of them. Paired with Infernal Affairs is Naledi Jackson’s utterly dynamic short film The Drop In. It pits a former special agent, now working at a hair salon, against an unusual - and possibly familiar - client.
