Netflix’s ‘Granny’ K-Drama Starts Filming in July 2026 — Lee Jung Eun and Kim Mu Yeol Lead the Revenge Thriller

Netflix is turning another hit webtoon into a live-action series, and this one might be its most unexpected action-thriller yet. “Granny”, based on the popular Korean webtoon by Jae Hu, is officially moving forward with production set to begin in July 2026. The series stars Lee Jung Eun and Kim Mu Yeol. If the premise doesn’t already grab you—a grandmother going after the criminals who hurt her grandson—then the cast definitely will.

What’s the Story?

“Granny” centers on Jung Suk Ja, a 70-year-old woman whose whole world revolves around her grandson, Kwon Yong Hui. When a violent attack leaves him in a coma and the members of the Black Star gang responsible walk free, Jung Suk Ja refuses to accept the injustice. Instead, she transforms herself into a vigilante, training to take down the very people the law couldn’t touch. It’s part action-thriller, part emotional family drama, and exactly the kind of high-stakes revenge hook that K-drama fans love.

Who’s In It?

Lee Jung Eun, the powerhouse actress from Netflix’s “The Frog” and “The Uncanny Counter,” takes the lead as Jung Suk Ja. Opposite her is Kim Mu Yeol, known for “The New World” and “The Age of Shadows,” in a key role. The project is directed by Han Dong Wook and produced through a collaboration between Sanae Pictures and Studio Dragon—the same production muscle behind many of Netflix’s biggest Korean hits.

When Will It Premiere?

Filming begins in July 2026 and is expected to run for several months, wrapping in early 2027. That schedule likely points to a late 2027 Netflix release, though Netflix has not confirmed an exact date. Given the streamer’s track record with Korean originals, “Granny” could easily become one of its most talked-about global launches of 2027.

Netflix has already proven that webtoon adaptations can explode worldwide—just look at the success of “Sweet Home,” “All of Us Are Dead,” and “The Uncanny Counter.” With Studio Dragon handling production and a director like Han Dong Wook at the helm, “Granny” has the pedigree to join that tier. The mix of a tight revenge plot, a morally gray heroine, and a fresh take on the action genre makes it a must-watch before we even see a trailer.

Revenge dramas are having a serious moment, but “Granny” flips the genre by putting a grandmother in the action-hero seat. With Lee Jung Eun’s commanding screen presence, Kim Mu Yeol’s intensity, and a premise that mixes grief, justice, and thrills, this could be Netflix’s next breakout K-drama. Mark your calendars for late 2027 and keep an eye out for more casting news.
