A meticulously crafted Swiss watch of mistaken identities, espionage, and colonial intrigue, Project A 2 may be Chan’s greatest accomplishment as a filmmaker. Chan keeps four separate subplots whirling through the air with the greatest of ease, while leaving time not just for intense action and groundbreaking stunts, but for some extraordinary non-action filmmaking. No comedy director has ever topped the intricacy of the famous nine-minute scene set in a two-room apartment that takes the conventions of French farce and turns them up to 11.
