The production of the highly anticipated second season of the Disney+ original series Moving has officially commenced, but not without significant controversy regarding its lead cast. According to reports from multiple broadcast officials, Won Kyu Bin has been cast to take over the role of Kim Bong Seok, the fan-favorite protagonist who possesses the powers of flight and heightened senses. This casting decision comes as the original actor, Lee Jung Ha, who rose to international stardom through the role, has recently begun his mandatory military service, rendering him unavailable for the upcoming filming schedule.
The transition began in earnest as Won Kyu Bin joined the Season 2 cast and production team at KINTEX in Ilsan for an initial script reading session. This event served as the formal launch of the new season’s production cycle, yet the atmosphere surrounding the announcement has been tempered by a vocal and disappointed fanbase. Moving, which premiered in August 2023, was a landmark success for Disney+, garnering critical acclaim and a massive global viewership. Based on the popular webtoon by Kang Full, the 20-episode first season wove a complex narrative of "human weapons"—children with latent superpowers and their parents, who harbor dark secrets from their pasts while protecting their offspring from government exploitation.
The Cultural Impact and Success of Moving Season 1
To understand the intensity of the current backlash, one must look at the unprecedented success of the series’ debut. Moving was not merely a television show; it was a cultural phenomenon that revitalized interest in South Korean superhero narratives. The series dominated streaming charts across Asia and became the most-watched Disney+ local original series in several regions, including South Korea, Japan, and Southeast Asia.
Lee Jung Ha’s portrayal of Kim Bong Seok was central to this success. As the son of Lee Mi-hyun (played by Han Hyo Joo) and Kim Doo-shik (played by Jo In Sung), Bong Seok represented the emotional heart of the story. Lee Jung Ha earned widespread praise for his physical and emotional dedication to the role, which included gaining 30 kilograms (approximately 66 pounds) to match the character’s description in the original webtoon. His performance captured a unique blend of innocence, vulnerability, and burgeoning strength, making the character a relatable figure for audiences worldwide.
The chemistry between Lee Jung Ha and his co-star Go Youn Jung, who played Jang Hee-soo, was frequently cited by critics as a highlight of the series. Their "high school romance" subplot provided a grounded, human element to the high-stakes espionage and supernatural battles that defined the show. Consequently, the news that Lee would not return for the second season has been met with a sense of loss among the "Moving" community.
Mandatory Military Service and Production Constraints
The primary driver behind the recasting is the South Korean legal requirement for mandatory military service. All able-bodied South Korean men are required to serve in the armed forces for a period ranging from 18 to 21 months. For rising stars like Lee Jung Ha, the timing of this service often conflicts with long-term production schedules.
Production sources indicate that the timeline for Moving Season 2 could not be delayed to accommodate Lee’s discharge. Given the massive scale of the production, the schedules of A-list veterans like Jo In Sung and Han Hyo Joo, and the pressure from Disney+ to capitalize on the first season’s momentum, the decision was made to proceed with a new actor. Script readings are often the point of no return for such productions, signaling that the creative direction and casting are finalized for the upcoming shoot.
While recasting is common in Western television franchises, it is relatively rare for a lead role in a high-profile K-Drama to change hands between seasons, especially when the original actor was so closely identified with the character’s identity.
Fan Reactions and the Demand for Narrative Continuity
Social media platforms have been flooded with reactions from fans expressing their disapproval of the casting change. The prevailing sentiment among the audience is that Lee Jung Ha’s portrayal of Bong Seok was "irreplaceable." On platforms like X (formerly Twitter) and various online Hallyu forums, fans have voiced their frustration, with many arguing that the production should have waited for Lee’s return.

One widely shared sentiment suggested that the writers should have modified the script to explain Bong Seok’s absence in Season 2, perhaps by focusing on other characters or introducing a time-skip that would allow Lee Jung Ha to reprise the role in a potential Season 3. "I refuse to believe I won’t be seeing Jung Ha as Bong Seok again," wrote one fan, echoing the thoughts of thousands who felt a deep emotional connection to the original actor’s performance.
Critics of the recasting also pointed out that Bong Seok’s physical appearance and mannerisms were so specifically crafted by Lee Jung Ha that any other actor would inevitably feel like an imitation. The controversy highlights the growing influence of "fandom" in the streaming era, where viewers feel a sense of ownership over characters and the actors who play them.
Introducing Won Kyu Bin: The Challenge of a New Lead
Won Kyu Bin, the actor selected to fill Lee Jung Ha’s shoes, faces an uphill battle. While he is recognized as a capable performer with significant potential, he enters the production under the shadow of his predecessor. The script reading at KINTEX was his first official appearance as Bong Seok, and while industry insiders report that he showed great promise during the session, public opinion remains skeptical.
The production team has expressed confidence in Won Kyu Bin’s ability to bring a "new dynamic" to the character. It is expected that Season 2 will delve deeper into the characters’ transition into adulthood, potentially allowing Won to interpret an older, more mature version of Bong Seok that differs from the high school student seen in the first season. However, whether the audience will accept this transition remains the most significant question mark hanging over the production.
Broader Implications for Disney Plus and the K-Drama Industry
The decision to recast in Moving Season 2 reflects a broader shift in the South Korean entertainment industry toward multi-season formats. Traditionally, K-Dramas have been single-season limited series. However, the rise of global streaming platforms has encouraged the development of long-running franchises. This shift brings new challenges, particularly regarding cast availability and the management of long-term narratives.
For Disney+, Moving is a flagship property. The platform has invested heavily in original Korean content to compete with rivals like Netflix. Any perceived dip in quality or loss of audience engagement due to casting changes could have financial implications for the service’s growth strategy in the Asian market. The success or failure of Won Kyu Bin’s Bong Seok will likely serve as a case study for other production houses facing similar dilemmas with military enlistment or scheduling conflicts.
Timeline of Events and Expected Release
The development of Moving Season 2 has followed a deliberate timeline:
- August 2023: Release of Moving Season 1 to global acclaim.
- Late 2024 – Early 2025: Rumors of a second season begin as creator Kang Full hints at expanding the "Kang Full Universe" (including webtoons like Bridge and Hidden).
- Early 2026: Lee Jung Ha formally enlists in the military.
- April 2026: Official announcement of Won Kyu Bin’s casting and the commencement of script readings at KINTEX.
- Late 2026: Principal photography is expected to continue throughout the year.
While an official release date has not been set, industry analysts predict that Season 2 will likely premiere in mid-to-late 2027, given the extensive post-production and visual effects required for the series’ supernatural sequences.
Conclusion: A High-Stakes Gamble for the Franchise
As production moves forward, the team behind Moving Season 2 finds itself in a precarious position. On one hand, they have the opportunity to expand one of the most creative and successful stories in recent television history. On the other, they must navigate the intense loyalty of a fanbase that remains unconvinced by the change in leadership.
The recasting of Kim Bong Seok is more than a simple logistical fix; it is a test of the franchise’s strength. If the writing and Won Kyu Bin’s performance can capture the essence of the character while offering something fresh, the show may overcome the current controversy. However, if the "new" Bong Seok fails to resonate, Disney+ may find that the superpower of flight isn’t enough to keep the series’ ratings airborne. For now, all eyes are on the production at KINTEX as the cast and crew attempt to build a future for Moving that lives up to its prestigious past.
