Zahn was born in Marshall, Minnesota, the son of Carleton Edward Zahn, a Lutheran minister, and Zelda Clair Zahn, a bookstore clerk and later a YMCA administrator. His father is of German and Swedish descent, and his mother is of German ancestry. Zahn spent part of his childhood in Mankato, Minnesota, attending Kennedy Elementary School, and moved to the suburbs of Minneapolis for high school, where he acted in school plays and became a two-time Minnesota state speech champion. He graduated from Robbinsdale Cooper High School in 1986, planning eventually to join the United States Marine Corps.\n', '
Zahn attended Gustavus Adolphus College for one semester but dropped out after seeing the original West End production of Les Misérables. "I remember sitting through the second act thinking, I’m good as that guy standing on the barricade," Zahn recalled. "I wanted to be part of the circus." In 1987, Zahn made his professional stage debut in a Minnesota production of Neil Simon\'s Biloxi Blues after falsely claiming to be a member of Actors\' Equity. His fellow actors suggested that Zahn study acting, inspiring him to enroll in American Repertory Theater\'s two-year training program. At A.R.T., he worked with the venerated stage director Andrei Șerban.\n', '
