Oliver K. Wnuk was born in Konstanz on January 28 1976. Before he had formal training as an actor, he already appeared in theatre plays in his hometown. From 1996 until 2000, he studied acting at the Bayerische Theater-Akademie August Everding in Munich. During that time, he performed at the Akademietheater and the Bayerische Staatsschauspiel, and had first roles in short films and TV productions.

In 2000, Wnuk made his debut in a theatrical release with the horror movie "Anatomie" ("Anatomy"). He went on to play supporting roles in "Gott ist ein toter Fisch" (2001), the box office hit "Der Schuh des Manitu" ("Manitou's Shoe", 2001), "Kiss and Run" (2002) and "Soloalbum" ("Solo Album", 2003).
