With over a decade in the Korean entertainment industry, it seems impossible for anyone not to recognise Oh Jung-se’s face. The veteran actor has appeared in Korean films and TV shows since the early 2000s, as well as a string of commercials for brands like McDonalds and Ridi Books in South Korea.

Dubbed by his Korean fans as “a millionaire of characters” for his acting range, Oh gained international recognition for his heart wrenching performance as an adult man with autism in the 2020 hit drama It’s Okay to Not Be Okay. This year, he returns in TVN’s 15th Anniversary Special Drama, Jirisan.
