According to Koreaboo, Lee Kwang Soo is an incredibly versatile actor, having appeared in many popular films and dramas, including the epic action-adventure film “The Pirates: The Last Royal Treasure,” the horror-disaster comedy “Sinkhole,” and the mystery series “The Killer’s Shopping List,” in which he starred alongside AOA’s Seolhyun.
Despite his massive list of accomplishments, many fans agree that one of Lee Kwang Soo's most notable activities is being a regular cast member of the variety show Running Man.
He has captured the attention of international fans for his dedication to the show's games and endless list of iconic comedic moments.


After leaving in 2021, Lee Kwang Soo still kept in touch with his former show co-stars, showing that their relationship went beyond work.
During an appearance with Ji Suk Jin on the entertainment show Pinggyego on YouTube channel DdeunDdeun hosted by MC Yoo Jae Suk, Lee Kwang Soo reunited the two Running Man members.
The show follows Yoo Jae Suk as he finds meaningless reasons to talk to his various celebrity friends. With Lee Kwang Soo and Ji Suk Jin as special guests, the trio begins to reminisce about their time on Running Man.

Yoo Jae Suk shared that he has always been close to Ji Suk Jin but first met Lee Kwang Soo through another drama called “Come To Play”. Their interactions made Yoo Jae Suk think that Lee Kwang Soo would be great if he appeared on variety shows.
On the contrary, when he first met Lee Kwang Soo, Ji Suk Jin did not think Kwang Soo would be suitable for variety shows. This proves that "national MC" Yoo Jae Suk always has a keen eye for discovering potential faces.
Lee Kwang Soo shared that before joining Running Man, Yoo Jae Suk encouraged him by saying he was very funny.
Then, when the Running Man producers asked who they should cast for the show, Yoo Jae Suk recommended Lee Kwang Soo. Ultimately, that choice helped Lee Kwang Soo gain thousands of fans around the world and propel his career to superstardom.
