“Frozen 2” is making such a killing in South Korea that it must be illegal, a civic group says.

The Public Welfare Committee complained to South Korean prosecutors Sunday about the animated sequel’s dominance in the country’s movie theaters, news reports said.

The film appeared on more than 88 percent of Korea’s movie screens on Nov. 23 — a rate so high it violates the nation’s anti-monopoly law, the non-governmental organization charged in a complaint against Walt Disney Company’s Korean arm.

Disney has “attempted to monopolize the screens and seek great profit in the short term, restricting the consumer’s right to choose,” the complaint said, according to The Hollywood Reporter.

“Frozen 2” has exploded at South Korean box offices since its Nov. 21 opening there, racking up some $61.1 million in gross revenue and selling more than 8.6 million tickets, data from the state-run Korean Film Council show.

The Public Welfare Committee alleges that the wide distribution of the film is “a case of one business occupying more than 50 percent of the market and constitutes a violation of the antitrust law,” the Yonhap News Agency reported.

But the film council uses a different calculation that puts the movie’s screen share at 46.3 percent on Nov. 23 rather than 88 percent, according to the Korea Herald.

Korean law governing movie screening does not limit the percentage of screens that can be allocated to a single film. But the Ministry of Culture, Sports and Tourism has said it would consider imposing such a cap amid concerns about big-budget movies dominating the market, reports said.

Disney did not immediately respond to a request for comment Monday morning.
