Seo Hyun-woo (born 20 November 1983) is a South Korean actor who began his career on stage and made his debut in a musical in 2010. In the same year, he won an acting award at The 9th Off Daehakro Festival.
Seo faced a period of obscurity that lasted for five years following his graduation. Seo naturally turned his attention to Daehakro plays and independent films. He starred as the main lead in Hyung Seul-woo's film Allergy (2015) that received the grand prize at the Fukuoka Independent Film Festival. He also starred in Shin Dong-young's short film Hatred, which received an official invitation to the 70th Cannes Film Festival.
He is widely recognized for his portrayal of reporter Kim Moo-jin in the 2020 drama Flower of Evil. In 2022, Seo played the role of Sa Cheol-seong in Park Chan-wook's film Decision to Leave. His performance earned him the New Actor Award at the 21st Director's Cut Awards.
Early life and education Seo was born in Busan on 20 November 1983. He attended elementary and middle school in Tongyeong before moving to Gongju, South Chungcheong Province, to attend , a prestigious boarding school. His alumni include actors Park Jeong-min and Cho Hyun-chul.
In high school, Seo was known for his lively personality and served as both class president and vice president. However, he felt a lack of direction due to the immense academic pressure. This changed at the end of his first year when he saw a school play for the first time, written by his literature teacher. Inspired by the performance, he joined a theater class in his second year, which helped him manage his emotions. Despite his newfound passion for acting, he kept it a secret from his parents and lacked the courage to pursue it professionally.
He enrolled in the English literature department at Kookmin University, believing that excelling in English was important. He soon felt that this path was not for him, as many of his classmates had more experience living in English-speaking countries. Feeling lost and facing challenges, he took a hiatus after his first year. He worked as a bartender in Daehak-ro, where he encountered the local theater scene, which reignited his desire to become an actor. "Every night, theater people from Daehak-ro came to the bar where I worked. They were like uncle figures, but they engaged in serious discussions every night. They recited lines from Greek tragedies like Sophocles and Aeschylus, and they pondered if Hamlet felt this way or if Othello's anger was like this. I secretly observed them every night. I'm not sure if this expression is appropriate, but it was like 'adults playing make-believe.' It was cool. And I was curious about what made them so obsessed. It was from this time that I made up my mind to become a real actor." He then appeared in the Korean production of Kiss Me, Kate, a musical based on William Shakespeare's The Taming of the Shrew. From July 9 to August 14, 2010, he played the character Ralph at the National Theater Haeoreum Theater.
In 2011, Seo began his on-screen acting career with a role in the film White: The Melody of the Curse (2011). That same year, he took on a darker role as Malcolm in Lee Young-seok's production of Shakespeare's Macbeth. This production was staged by the troupe Elephant Manbo at the Jeongmiso installation theater as part of a performance commemorating the troupe's 25th anniversary and the 2011 Guerrilla Theater Overseas Director Special Exhibition.
In March 2012, Seo appeared in the three-person play Hamlet, directed by Seong Cheon-mo. In this unique adaptation, he played Campbell, while Ryu Ji-wan played Hamlet and Jeong Soo-young portrayed five different characters, including Ophelia and Queen Gertrude. The play ran at the Seoul Arts Center's Jayu Theater until May 6. Seo portrayed Doo-su, a detective in Fatal Intuition. Doo-su suspects Jang-woo (played by Joo Won), of being a murderer. Through his performance, Seo effectively depicted a seasoned character who skillfully balances with the harsh realities of the situation. Seo, being a native of Busan, played a crucial role in assisting Joo Won with his acting in the movie. Joo Won had to deliver all his lines in the Gyeongsang dialect, and for two months, he received private tutoring from Seo. Furthermore, at the director's request, Seo created personalized textbook containing all of Joo Won's lines, which he personally recorded.

He appeared in episodes 7 and 8, broadcast on July 29 and July 30, respectively, and received favorable reviews for his performance.

To win the trial, he demonstrates his cool-headedness by collecting GPS data from a car's navigator after the evidence inside the vehicle was nullified due to illegal handling.
That same year, Seo did two back-to-back plays with the Aligator Theater Company. He reprised his role as Lee in the Korean encore performance of Sam Shepard's play True West Return.

He played Kim Moo-jin, a reporter who is described as carefree, self-centered, and cunning. His character's life becomes complicated when he encounters Do Hyun-soo (Lee Joon-gi), someone from his past who had caused him trauma. Kim Moo-jin also has a romantic relationship with Do Hyun-soo's older sister, Do Hae-soo (Jang Hee-jin). "It was my first lead role, so I felt pressured, but I was able to take on the role in an interesting way because it changes like a chameleon depending on the situation. I was really moved when I first started receiving calls after auditioning non-stop. I had really mixed emotions. It's my first time doing a melodrama, and it's my first time acting with someone my age. Even in my 20s, I mainly played roles older than my age, such as teacher rather than student, but everything was new to me. I got to discover new sides of myself while playing roles of people my age." In 2021, Seo participated in Exotic Garden, a live dubbing performance directed by Jeon Gye-soo that combines film with musical theater.
