Curt Lowens is dubbed by Dan O'Herlihy.
When David Christopher arrives in Zürich, he is first seen crossing the Quaibrücke at the mouth of the Limmat that flows northwards from the Zürichsee in his red 1971 Ferrari 365 GTS/4. He then turns onto Stadthausquai and parks next to the River opposite the Hurtil Bank. This building, which forms the shape of a trapezoid, is sandwiched between the aforementioned Stadtshausquai, Lochmannstrasse, Fraumünsterstrasse and Börsenstrasse, and now contains a pub, lawyer's offices, various doctors and Forum SNB (Swiss National Bank).
