Burger King Korea ended its Whopper campaign amid a film-boycott storm

Burger King Korea launched its autumn Truffle Mushroom Whopper in September 2026 with actor Yoo Hae-jin fronting a wordplay campaign built on his name — a standard star-plus-menu launch in a market where celebrity models drive fast-food sales.

The Truffle Mushroom Whopper campaign leaned on wordplay pairing Yoo's name with the word 'new' — until the film controversy swallowed the launch.

After controversy erupted over 'The Assassin' — the film Yoo stars in, which depicts the 1974 shooting of former first lady Yuk Young-soo — conservative group Sinjayunyondae and right-leaning YouTubers rallied outside his home calling the film a distortion of history, and boycott posts showed users deleting the Burger King app. Protest comments flooded the ad videos; Burger King disabled their comment sections, posted a notice that all campaign models work under one-time contracts, and Yoo's videos came down while other models' remained.

The campaign ended within weeks of launch. Burger King maintained the conclusion followed the originally planned schedule and was unrelated to the controversy; observers read the removal of Yoo's ads as boycott-driven. Police stepped up patrols for the actor at his agency's request.

In September 2026, Burger King Korea launched its autumn menu item, the Truffle Mushroom Whopper, with an advertising campaign built around actor Yoo Hae-jin and a wordplay concept combining his name with the word 'new'. Within weeks the campaign was over, caught in a storm that had nothing to do with burgers.

The backlash came from 'The Assassin', the film in which Yoo plays the lead role, which is based on the 1974 shooting of first lady Yuk Young-soo at a Liberation Day ceremony. On the Sunday before the campaign's end, the conservative group Sinjayunyondae and several right-leaning YouTubers held a rally outside Yoo's home in Seoul, calling the film a distortion of history and demanding boycotts of the products he endorsed.

Posts on online communities showed users certifying boycotts and deleting the Burger King app; protest comments flooded the brand's advertisement videos, prompting Burger King to disable the comment sections. The company posted a notice that all its campaign models work under one-time contracts and that the Truffle Mushroom Whopper model's scheduled activities had concluded — then removed Yoo's videos while other models' ads stayed up. Police said they received a personal safety request from Yoo's agency and stepped up patrols.

A celebrity-led launch inherits the star's entire public context: the film's subject matter became the campaign's context overnight.

The boycott targeted endorsement itself — 'actors bear responsibility for the works they appear in' — so no amount of menu appeal could separate the Whopper from the film.

Burger King's response stayed procedural — one-time contracts, scheduled conclusion, disabled comments — avoiding a statement on the film either way.

The quiet removal of Yoo's ads while other models' remained showed the practical outcome regardless of the official line.

Casting is a bet on the celebrity's whole news cycle: a brand can be dragged into a history fight it has nothing to say about.

As of 7 October 2026, Yoo Hae-jin's campaign videos were no longer on Burger King's site while other models' remained; the company repeated that the campaign ended on its original schedule, and police continued protective measures around the actor.
