Lee Sang-geun built his reputation on a single ruthless trick: drop two charismatic leads into an impossible bind and watch them scramble out. In Pretty Crazy, the bind is a woman who turns into a devil at two in the morning, and the man asked to survive her is an unemployed slacker with nothing better to do. The film struggled to fill seats in Korean cinemas, then found a far larger audience the moment it reached Netflix.

YoonA, the Girls’ Generation singer turned actor, plays Seon-ji, a bakery apprentice whose daytime sweetness curdles into something horned and feral after midnight. Ahn Bo-hyun is Gil-gu, the broke neighbour her family pays to babysit the nocturnal version while he quietly falls for the daytime one. Lee, whose disaster comedy Exit turned a rooftop escape into one of Korea’s biggest crowd-pleasers, wrote this script long before he had the standing to make it, then reopened the file once Exit handed him the clout.

The conceit is engineered for a star willing to make herself ugly. By day Seon-ji is shy and conscientious; once the clock turns, she becomes a foul-mouthed wrecking ball who treats Gil-gu as her personal servant, and the comedy lives in the whiplash between the two. It is a romance built on a horror premise and played almost entirely for laughs, with the mystery of why the curse exists threaded underneath. The Korean title, The Devil Moved In, is the blunter description; the international release leans on the wink of Pretty Crazy.

Lee works in a narrow, lucrative lane. Exit took a stalled millennial and his college crush and chased them up the side of a city choking on toxic gas, turning rock-climbing trivia into life-or-death slapstick. The method carries over here: one outlandish premise, two appealing performers, and a structure that keeps raising the stakes until the laughs and the tension fuse. When it works, as Exit did with more than nine million admissions at home, the result is genuinely crowd-pleasing. When the premise runs thinner, the machinery starts to show.

CJ Entertainment opened the film in Korean theatres on 13 August 2025, and it underperformed against the wattage of its cast, grossing in the region of 3.1 million dollars. The reversal arrived on 26 November 2025, when Netflix added it worldwide and the title climbed to the top of the platform’s film chart. The streaming run delivered the hit that domestic ticket sales never did, and slotted Pretty Crazy into a now-familiar pattern: a Korean film that shrugs off a soft theatrical opening to become a global watch-at-home phenomenon weeks later.

The theatrical run was not a critical write-off either. YoonA took Best Actress at the Chunsa Film Art Awards and the year’s Viewers’ Choice prize, and landed a Best Actress nomination at the Blue Dragon Film Awards; Ahn Bo-hyun won Best New Actor at the same ceremony. Read together, those results reframe a modest box-office tally as a performance showcase that audiences simply caught up with late, and they cement YoonA’s slow migration from idol stages to roles that ask her to look genuinely unhinged.

For YoonA, the role is another step away from the idol stage. She has spent recent years building a screen career across television and film, leaning on comic timing and a willingness to abandon the polished image that made her famous, and Seon-ji is the most extreme version of that instinct yet. The devil half of the part is all bared teeth and bad behaviour, the kind of unflattering, physical performance that award juries rewarded and that gives the film its clearest reason to exist beyond the high concept.

Now the film takes another theatrical swing abroad. It opens in Japanese cinemas on 19 June 2026, retitled Pretty Crazy: The Devil Moved In, after a trailer arrived there in the spring. The sequencing is unusual. A title already streaming around the world is heading back to the big screen in a fresh market, betting that YoonA’s regional pull and the devil-after-dark premise still move people to buy a ticket rather than wait for the stream.

What the Japanese run cannot prove is that the gimmick travels. Pretty Crazy leans hard on its one supernatural conceit, and the warmest notices at home went to YoonA’s physical comedy rather than to a romance that settles into familiar shapes once the novelty of the transformation fades. A chart position measures curiosity, not staying power, and a theatrical re-release for a film viewers can already stream at home is a wager on star loyalty more than on word of mouth. Whether Japanese audiences turn out for a cinema ticket is the real test the Netflix numbers leave unanswered.

For most of the world, Pretty Crazy is already a click away: Netflix has carried it globally since late November. Japanese audiences get the cinema version from 19 June 2026.
