Artificial intelligence is creating a new kind of risk for South Korea’s entertainment industry, where a single online controversy can freeze television productions, unravel endorsement contracts and erase millions of dollars in commercial value before investigators determine whether the underlying evidence is authentic.
That reality is now being tested by the return of South Korean actor Kim Soo-hyun, one of the country’s biggest television stars whose hit dramas, including It’s Okay to Not Be Okay and Queen of Tears, helped make him one of Asia’s most sought-after advertising endorsers.
Kim resumed official activities this week by filming a new advertising campaign for Philippine apparel retailer Bench, marking his first public commercial appearance in 16 months. The comeback follows a scandal that sidelined one of South Korea’s most valuable entertainment brands and exposed how rapidly AI-generated content can influence public opinion and corporate decisions.
The controversy began after allegations circulated online that Kim had dated the late South Korean actress Kim Sae-ron while she was underage. Kim’s management company, Gold Medalist, denied the allegation from the outset, maintaining that their relationship began only after she reached adulthood.
As the accusations spread across social media and online platforms, the commercial fallout was immediate. Disney+ suspended production of Knock-Off, a series built around Kim, while several companies that had hired him as a brand ambassador sought compensation for alleged financial losses. Combined civil claims from advertisers total about $6 million.
Months later, investigators reached a conclusion that fundamentally changed the case. South Korean authorities determined that voice recordings and KakaoTalk conversations presented as key evidence had been manipulated using artificial intelligence, shifting attention from the allegations themselves to the growing challenge of AI-generated misinformation.
The investigation also led prosecutors to indict Kim Se-ui, operator of the South Korean YouTube channel Garosero Research Institute, on charges including criminal defamation involving false information, stalking-related offenses, attempted coercion, intimidation and the distribution of illegally recorded material. The criminal case continues separately from the civil litigation involving Kim’s endorsement contracts.
For South Korea, the case extends well beyond a single celebrity. The country’s global entertainment business relies heavily on actors and musicians whose commercial value supports streaming platforms, international licensing agreements and marketing campaigns across Asia and beyond. In that environment, allegations amplified through digital platforms can disrupt productions and business relationships long before legal authorities establish whether the evidence is genuine.
Kim’s appearance in the Bench campaign does not resolve the lawsuits or guarantee the return of suspended projects. Instead, it represents an early measure of whether South Korea’s entertainment industry—and the companies investing in its biggest stars—is prepared to restore commercial confidence after a scandal in which AI-generated evidence proved nearly as influential as verified facts themselves.
