How Lee Kwang Soo's Gold Tooth Made 'Goldland' Go Viral

A single golden tooth has become the most talked-about detail in one of Korea's hottest new dramas — and the actor who came up with it wants everyone to know it was entirely his idea.

On Wednesday, Disney+ Korea uploaded a commentary video for the first four episodes of "Goldland," their acclaimed new thriller starring Park Bo Young and Lee Kwang Soo. Titled "Everyone Has Desires," the video gave cast members a chance to reflect on the drama's making. It was there that Lee Kwang Soo revealed the origin story of his character's now-iconic gold tooth, setting off a lighthearted but pointed dispute with the director over who actually deserves the credit.

The Gold Tooth Debate

According to Lee Kwang Soo, he researched tooth gem designs on social media, assembled a selection of options, and presented them directly to director Kim Sung Hoon with a specific proposal. The director approved the idea at the time. But once audiences responded enthusiastically to the detail — and it became one of the most talked-about visual elements in the show — the director, Lee claimed, began describing the gold tooth as his own creative vision.

"I came up with it," Lee said plainly in the commentary video, making clear that the credit belongs to him. Park Bo Young, watching alongside him, backed the story up — and noted that the gold tooth had become one of the drama's most memorable visual details, particularly during emotional scenes, where it catches the light in a way that adds an unsettling dimension to the character. The small flash of gold, she suggested, tells you something about Deputy Director Park that his face alone might not.

Kim Sung Cheol, the third lead, offered a different observation about Lee's performance: a subtle movement of the upper lip during moments of anger that, Sung Cheol said, communicates menace quietly and precisely, without any need for raised voices.

About Goldland

"Goldland" is a Disney+ original thriller series that premiered on April 29, 2026. Directed by Kim Sung Hoon, it follows Hee-joo (Park Bo Young), a woman who finds herself holding 150 billion won in gold bullion stolen from a smuggling operation. What follows is a survival thriller built around greed, betrayal, and the question of who, ultimately, gets to keep the prize.

The cast includes Park Bo Young, Kim Sung Cheol, Lee Kwang Soo, and a supporting ensemble that includes Kim Hee Won and Moon Jung Hee. The series is rated for adult audiences — which restricted its potential viewership from the start, making its chart performance all the more striking.

Park Bo Young's performance has drawn particular attention. Korean audiences familiar with her from romantic comedies like "Strong Woman Do Bong Soon" (2017) or the fantasy drama "Oh My Ghost" (2015) have watched her take on a morally complex character in a genre built on pressure and survival instinct. The response has been one of surprised enthusiasm: her portrayal of Hee-joo is being described as a genuine turning point in how she is perceived as an actor.

Global Charts and Viewer Reactions

The response to "Goldland" has been fast and emphatic. According to FlixPatrol data, the series reached number one on the Disney+ Top 10 TV Shows chart in South Korea for three consecutive days as of May 2, 2026 — a significant achievement for an adult-rated series airing during a national holiday week.

Internationally, the show charted in 19 countries, including Japan, Taiwan, Bolivia, Brazil, Peru, and Venezuela. For a Korean-language thriller without K-pop stars in its cast, that level of immediate global traction is notable. It points to a growing international audience for Korean genre drama beyond the typical fandoms.

Korean viewer reactions have been enthusiastic. "The immersion from episode one is insane," read one widely shared comment. "The direction is like a movie," read another. Critics and viewers alike have pointed to the series' visual texture and pacing as qualities that set it apart — tight, cinematic, and crafted for sustained tension rather than episodic payoffs.

Lee Kwang Soo's Evolving Range

Lee Kwang Soo spent most of his public career as one of Korea's best-known variety show personalities — a decade on "Running Man," where he built his reputation on physical comedy, self-deprecating charm, and a loveable haplessness that made him impossible not to root for. It served him well. It also created expectations that took real effort to move past.

He has been working steadily in drama and film for years, but "Goldland" is positioning itself as a more decisive statement. Deputy Director Park is not a comedic role. He is controlled, quietly threatening, and — in Lee's own words — "the most unchanging character" in the story. Where others shift allegiance or reconsider their choices, Deputy Director Park stays on course. In the context of "Goldland," that means remaining reliably dangerous.

The gold tooth, it turns out, is the right detail for a character like this: a small, conspicuous thing that always draws attention, that does not try to hide anything, and that you notice whether you want to or not. If Lee Kwang Soo did invent it — and by all accounts he did — he created something that makes his character harder to forget every time he appears on screen.

The Making of a Global Hit

"Goldland" is one of several high-budget original series that Disney+ has backed for the Korean market, positioning the platform as a serious contender for prestige Korean drama. What distinguishes this particular release is its genre commitment: where many Korean streaming originals hedge toward romance or family drama to maximize broad appeal, "Goldland" is a full-throttle adult thriller with no apologies and no softening.

Director Kim Sung Hoon's background in feature film production shows in the series' visual grammar. Scenes are held longer than Korean drama conventions typically allow, characters are observed rather than explained, and tension is built through composition and silence as much as through plot mechanics. It feels, as many viewers have noted, more like a twelve-episode film than a traditional drama in how it manages pace and image.

Whether it was Lee Kwang Soo's gold tooth or Kim Sung Hoon's direction — or both, working in concert — "Goldland" has arrived at a moment when Korean genre content is finding new audiences faster than platforms can produce it. The debate about who invented Deputy Director Park's most distinctive detail is, at heart, a testament to how closely audiences are now paying attention to what they watch.

Where to Watch

Episodes one through four of "Goldland" are currently available on Disney+. Episodes three and four were released on May 6, 2026. The Wednesday commentary video — featuring the gold tooth debate and other behind-the-scenes moments — is available on the Disney+ Korea YouTube channel for viewers who want a closer look at how the show was assembled and the choices that made it memorable.
