SBS’s new Friday-Saturday drama ‘Doctor X: The Age of the White Mafia,’ starring Kim Ji-won, will premiere at 9:50 p.m. on October 9, 2026. Following the release of information about the genre, protagonist, and main cast, the script reading and first stills have also been unveiled, making the details available before the broadcast more concrete.
Key Changes
The most significant development is that the premiere schedule has been confirmed. ‘Doctor X: The Age of the White Mafia’ is scheduled to premiere on SBS at 9:50 p.m. on Friday, October 9. The drama has moved beyond the stage where only its title was known, with a broadcast date and time now set for viewers to check.
Kim Ji-won plays Gye Soo-jung, a surgeon with genius-level surgical skills. SBS’s first stills also introduce Kim Ji-won appearing as Gye Soo-jung.
Gye Soo-jung, played by Kim Ji-won, has been introduced as a central figure who confronts the medical field and deep-rooted corruption.
Current Status
‘Doctor X’ is a medical noir depicting the exploits of doctor Gye Soo-jung as she confronts deep-rooted corruption. As suggested by the phrase ‘The Age of the White Mafia’ in the title, conflicts set in the medical world and clashes between the characters are expected to remain central points of interest. However, the drama’s medical settings and surgical scenes should be understood as storytelling and character-driven production elements, not as actual medical information or treatment guidance.
The main cast has also been announced. Lee Jung-eun plays Jang Hee-sook, Son Hyun-joo plays Boo Seung-kwon, and Kim Woo-seok plays Park Tae-kyung. The relationships and conflicts these three characters create alongside Kim Ji-won’s Gye Soo-jung will be revealed through the broadcast.
On September 1, SBS released a behind-the-scenes clip from the script reading through its official SBS Catch page. The script reading video shows the production process as the actors first establish the tone of the series and align their interpretations of the characters.
Impact
With the premiere date confirmed, ‘Doctor X’ has entered a stage where viewers can begin planning when to watch. With its Friday 9:50 p.m. SBS time slot clearly established, viewers who have been waiting for Kim Ji-won’s new role can use the premiere date as a reference for following related content.
The main focus of attention is Kim Ji-won’s transformation into the character. Gye Soo-jung is written as a surgeon with genius-level surgical skills, and the series follows her as she confronts deep-rooted corruption. With character information about Lee Jung-eun, Son Hyun-joo, and Kim Woo-seok also available, attention is turning not only to the protagonist’s personal changes but also to the conflicts among the major characters.
The release of the script reading footage and first stills provides official material for checking the drama’s direction before its premiere. The stills visually show Kim Ji-won appearing as Gye Soo-jung, while the behind-the-scenes clip indicates that production has progressed to the stage of releasing material from the script reading.
There is no official material confirming that Kim Soo-hyun will appear in ‘Doctor X’ or that he will make a comeback in this series alongside Kim Ji-won. Interpretations linking the two actors’ appearances are not included in the currently released cast information for ‘Doctor X.’
Next Checkpoint
The clearest schedule to note is the premiere of ‘Doctor X: The Age of the White Mafia’ on SBS at 9:50 p.m. on Friday, October 9, 2026. Before the broadcast, information about the series can be checked again through SBS’s official program introduction page and its official content channels.
Viewers waiting for the drama can first review the basic information, including its genre, Kim Ji-won’s role as Gye Soo-jung, and the announced main cast. They can then explore the series’ tone through SBS’s released script reading behind-the-scenes clip and first stills. Because screenplay and directing credits vary across some official materials, it is more accurate not to treat any specific listing as definitive until further official information is released.
