Although he appeared in over 100 films, Jürgens was also a notable stage actor. He was member of several theatres in Vienna (Volkstheater 1938–1941, Burgtheater 1940–1953 and 1965–1968, and others). He played the title role of Hugo von Hofmannsthal's play "Jedermann" at the Salzburg Festival from 1973 until 1977 – arguably the most high-profile role for a German-speaking male actor. In 1966 he appeared in a short run on Broadway at the Eugene O'Neill Theatre opposite Geraldine Page, directed by George Schaefer.
