Choi Kwang Il, who has been drawing attention for his intense performance in SBS's hit medical drama Doctor X: Age of the White Mafia, is gaining renewed interest after his family connection to legendary actor Choi Min Sik came into the spotlight.

The actor, who plays one of the drama's powerful antagonists, is actually Choi Min Sik's younger brother, with an eight-year age difference between them.

In Doctor X, Choi Kwang Il portrays Goo Bon Pyeong, the chairman of the Guseo University Hospital Foundation and leader of the influential Magnolia Society.

His character holds considerable power within the hospital and frequently clashes with the medical team, including Gye Su Jeong, played by Kim Ji Won.

Through his commanding presence and strict personality, Choi Kwang Il has added tension to the drama, particularly during confrontations involving the hospital's leadership and medical staff.

However, beyond his performance, attention is now turning to his surprising connection with one of South Korea's most respected actors.

Choi Kwang Il, born in 1970, is the younger brother of Choi Min Sik, who was born in 1962 and is widely known for his performances in films such as Oldboy and The Admiral: Roaring Currents.

Despite having a famous older brother, Choi Kwang Il reportedly chose to build his acting career without publicly emphasizing their family relationship.

While Choi Min Sik made his television debut in 1989, Choi Kwang Il began his acting career on the theater stage in 2001, spending years developing his experience before becoming more active in television dramas.

He gained wider recognition through tvN's Prison Playbook in 2017 and later appeared in several popular productions, including The Uncanny Counter, Alchemy of Souls, The Glory, and When the Phone Rings.

His growing list of roles helped him establish his own reputation as a supporting actor, separate from his older brother's successful film career.

Interestingly, Choi Kwang Il previously shared a lighthearted story about how the brothers react to each other's acting.

During a 2021 special program for The Uncanny Counter, he was asked what Choi Min Sik thought about his performance.

“He didn't say much. He just told me, 'You really played such a bad person,'” Choi Kwang Il recalled.

He added that their conversations about acting are usually casual.

“When I watch my brother's work, I also say things like, 'I enjoyed watching it. You really played a bad person,'” he shared.

The amusing exchange offered a glimpse into their relationship, showing how the two actors talk about each other's performances without making a big deal out of their achievements.

Now, with Choi Kwang Il continuing to portray a powerful antagonist opposite Kim Ji Won in Doctor X, his family connection to Choi Min Sik has become another point of interest surrounding the drama.

Despite sharing a family name with one of Korean cinema's biggest stars, Choi Kwang Il has spent more than two decades building his own acting career through theater, television, and film.

Doctor X: Age of the White Mafia continues to air every Friday and Saturday on SBS.
