Career
Beginning
Um Tae-goo's career began with the public release of his first short film, Season's End (2003). His early minor roles in Lady Vengeance (2005) and Epitaph (2007) came in projects where his older brother, film director Um Tae-hwa, served as an assistant director and encouraged him to audition. Prior to Um Tae-goo's full-time acting career, his brother had already established himself by directing short films such as Cactus and Fill the Hole in My Wisdom Tooth, and by working on various commercial films.
The film Epitaph (2007) marked Um's official acting debut, in which he secured a role as a Japanese soldier. Despite diligently memorizing his lines, nervousness—due to this being his first role with dialogue—caused him to forget them, leading to filming delays. He remained on the mountain set, wearing his costume and repeatedly practicing his lines while skipping meals, which led a hiker to mistake him for a real armed guerrilla.
From 2007 to 2010, Um primarily took on bit roles. In 2010, he collaborated with his brother for the third time in the short film Home Sweet Home (Yusukja), where he was cast as a homeless man after another actor dropped out due to the need for a shaved head.
In 2011, Um had small roles in several films, including Insadong Scandal, The Servant, I Saw the Devil, Oki's Movie, and Spellbound.

The film depicts a family falling apart due to the mother's (Gil Hae-yeon) involvement in a pyramid scheme, with Um portraying Youn-ho, a son grappling with debt and a broken engagement.
