Disney+ has unveiled a Sept. 10 global premiere date for its tentpole K-drama series Tempest, a nine-part international espionage thriller headlined by Korean A-listers Gianna Jun (Jun Ji-hyun) and Gang Dongwon, alongside U.S. actors John Cho and Michael Gaston. The series will debut with a three-episode launch on Disney+ internationally and Hulu in the U.S., followed by weekly drops culminating in a two-part finale on Oct. 1.
Directed by Queen of Tears showrunner Kim Heewon and penned by regular Park Chan-wook collaborator Chung Seokyung (Decision to Leave, The Handmaiden), Tempest unfolds in the shadow of an attempted assassination on a South Korean presidential candidate. As the investigation spirals into a web of state secrets, cross-border intelligence, and clandestine alliances, a former UN ambassador (Jun) and a morally conflicted mercenary (Gang) are pulled into an international conspiracy with ramifications stretching to the White House.
The series marks Jun’s debut on Disney+ and assembles one of the most globally diverse casts to date for a Korean drama, including Cho (Star Trek), Gaston (Bridge of Spies), and Spencer Garrett (Once Upon a Time… in Hollywood). Also starring are Lee Misook, Park Haejoon and Christopher Gorham.
Tempest is co-directed by veteran action choreographer Heo Myeonghaeng (The Roundup: Punishment) and produced by Imaginus in association with Showrunners, AA, and Skydance.
The release of Tempest comes amid some growing momentum for Disney+ in the Korean drama space. The platform scored a major win earlier this year with Nine Puzzles, the most-watched Korean original on Disney+ in 2025 to date. Tempest is positioned as one of the streamer’s top K-content titles for the second half of the year — aiming for buzz with its starry cross-border cast, elite creative team and timely storyline.
