O Taeseok is most well-known as a
theatre director and
playwright who is extremely adept at portraying Korean life and state of mind. O Taeseok's plays have many elements in common with traditional Korean plays. On stage the characters of his plays do not carry on static, realistic conversations, but rather engage in vibrant song and dance or wear animal masks while dashing about on stage; exaggerated movements and make-up are also frequently used. Despite the loud, raucous atmosphere on stage, O Taeseok's work depicts the darkness of pain and the shadows of death. The story behind this lies in his childhood memories. O Taeseok made his formal literary debut with his play
Wedding Dress (), which was recognized at the 1967 New Years Literary Arts Competition sponsored by
The Chosun Ilbo, and
Change of Season (), which won a prize in a 1968 open playwriting competition co-sponsored by the National Theatre and the Kyunghyang Daily News. In 1968 and 1969 his plays
Change of Season (),
Judas, Before the Rooster Crows (),
Outing (), and
Self-Righting Doll on Roller Skates () were performed in several avant-garde theatres. He next took up residence with the Dongnang Repertory Company (), where he directed
Lubeu (), and continued to direct and write. ==Works in translation==
