'Bad Girl: Run, Hani' turns 40: Na Ae-ri takes the lead in a trilogy set for October release

The iconic Korean animation that began as a 1985 comic and became a 1988 TV sensation returns as the theatrical 'Bad Girl: Run, Hani,' aiming for an early October bow with Na Ae-ri stepping from rival to lead, while the original's coming-of-age heart is reframed through friendship, teamwork, and grit; as producers note, this film is designed as the first act of a trilogy roadmap. MK Sports coverage has described the vibe as a feel-good revival tuned for modern audiences. Revisiting the world with Na Ae-ri in front, the creators lean into the "unfinished margins" of the rival's backstory to unlock fresh dynamics with Hani and friends, widening the emotional lens beyond the original's maternal longing arc. It positions the duo less as fixed opposites and more as catalysts for mutual growth, resonating with intergenerational fans who grew up on the original rivalry. The film trades traditional track lanes for S-Run, an urban sprinting sport that turns skylines, stairs, and alleys into a kinetic arena, promising set pieces that channel comic-book elasticity into big-screen momentum. This shift aims to fuse nostalgia with contemporary spectacle, keeping the run-in-your-veins spirit while updating the canvas. Music has been rebuilt to lodge scenes in memory, with long-form sequences structured almost like a music video to sustain adrenaline and uplift; the classic theme surfaces as a tasteful motif, a wink that rewards decades-long fans without freezing the story in amber. The approach aims for that leave-the-theatre-smiling feel the director has publicly championed. Producers frame this outing as part one of three, with the next chapter already drafted and teasing nationwide cityscapes, including a marquee stretch on Busan's waterfront for a sea-breeze sprint. The franchise plan signals confidence that Hani and Na Ae-ri's rebalanced journey can sustain an arc that honours legacy while sprinting into new narrative terrain.
