“We feel we decide our own fates, but we don’t.” Oscilloscope Labs has unveiled the official US trailer for a intriguing documentary film called Mistress Dispeller, which originally premiered at last year’s Venice Film Festival. It also played at tons of other fests, including Toronto, Zurich, Chicago, & Hot Springs, and will hit US theaters this October. Desperate to save her marriage, a woman in China hires a professional to go undercover and help break up her husband’s affair in an attempt to save her marriage. An intriguing look at a new industry in China featuring a woman known as “Mistress Dispeller” about couples who want to try & stay married. With strikingly intimate access, Mistress Dispeller follows this unfolding family drama from all corners of a love triangle. The production team followed different couples and love triangles for 3 years until they found one that stayed through to the end without withdrawing their consent. It looks much more profound than it sounds, not really criticizing the infidelity as much as exploring why marriages fail & how people can work on fixing their issues, whatever they may be. The poster art is also quite lovely – view below.

Here’s the official trailer (+ poster) for Elizabeth Lo’s film Mistress Dispeller, direct from YouTube:

In China, a whole new business industry has emerged devoted to helping couples stay married in the face of infidelity. Wang Zhenxi is part of this growing profession and is hired to go undercover and break up affairs by any means necessary; known as a “mistress dispeller.” Offering strikingly intimate access to a real, unfolding love triangle, Mistress Dispeller documents all sides of what is usually kept behind closed doors. As Teacher Wang attempts to bring a couple back from the edge of crisis, sympathies shift between husband, wife and mistress while emotion, pragmatism and cultural norms collide in this spellbinding look at modern love. Mistress Dispeller is directed by the indie producer / writer / filmmaker Elizabeth Lo, director of the doc film Stray previously, and many other short films. With writing by Elizabeth Lo and Charlotte Munch Bengtsen. Produced by Emma D. Miller, Elizabeth Lo, Maggie Li. This initially premiered at the 2024 Venice Film Festival last year and at many other fests.
