So Ji‑Sub, Joo Sang‑Wook, Choi Dae‑Hoon & Yoon Kyung‑Ho Light Up the ‘Agent Kim Reactivated’ Set

Fans of SBS’s hit drama Agent Kim Reactivated got a tasty glimpse behind the curtain when the network dropped a fresh making‑of video earlier this week. The clip opens with a quiet, almost choreographed rehearsal: So Ji‑Sub and Joo Sang‑Wook glide through an action sequence, each movement measured, each glance sharp.

Just when you think the tension is mounting, the wires do their magic and fling Joo Sang‑Wook backwards. He lands with a thud, but instead of a grimace, the camera catches So Ji‑Sub leaning over, offering a hand and a grin. It’s a tiny, candid moment that says a lot about their professionalism and, frankly, their camaraderie.

What really steals the show, though, is the comic relief provided by Choi Dae‑Hoon and Yoon Kyung‑Ho. As the two watch the stunt unfold, they start tossing witty asides and improvised lines that send everyone – including the usually stoic So Ji‑Sub – into a fit of laughter. Their ad‑libs are playful, off‑beat, and feel totally unscripted, turning a serious rehearsal into a mini‑comedy sketch.

Even after the camera rolls, the chuckles linger. It’s clear that the cast’s chemistry extends beyond the script, making the set feel more like a tight‑knit family than a work environment. By the way, this blend of hard‑won action and light‑hearted banter is probably one of the reasons the series wrapped up with a number‑one rating, sealing its place in this year’s drama hall of fame.

If you’re curious for more, the full making‑of video is available below. And while you’re at it, why not revisit So Ji‑Sub’s charming turn in Oh My Venus or catch Yoon Kyung‑Ho’s memorable performance in The Legend of the Kitchen Soldier on Viki? The talent behind Agent Kim Reactivated definitely deserves a second look.
