North Korean animation was thrust into the spotlight last month after the U.S. Treasury Department sanctioned Pyongyang’s SEK Studio. “Seemingly fueled by the desire for unreasonably low-cost labor, foreign media companies continue to subcontract animation work to SEK Studio,” the department said in a statement.

SEK Studio has been involved in at least 1,200 different films and television shows, according to IMDB, and it may have helped animate well-known American products like “The Simpsons” via South Korean subcontractors. North Korean talent may have even contributed to “The Lion King,” “Pocahontas” and others.
