Nick Cheung became one of Hong Kong's biggest stars on the strength of leading roles in action-comedies (The Conman), Triad flicks (Election), and boxing dramas (Unbeatable). So naturally his first two films as a director have been… ghost movies? Doubling down on his 2014 debut, Hungry Ghost Ritual, Cheung plays Fatt, a Triad gangster who moonlights as an exorcist. Since childhood, Fatt has been blursed (yup, that's 'blessed' + 'cursed') with the ability to see and communicate with the spirits of the deceased. But when called on to arbitrate disputes between the dead and the pre-dead (i.e., the living), Fatt doesn't bother with cryptic chants or rituals; instead, he practices gangster diplomacy by making the spirits an offer they can't refuse. Filled with wild special effects and superstar cameos, Keeper of Darkness isn't just a movie, it's a full-body visceral experience.
