"Director Miguel Alexandre (‘Greetings from Kashmir’) staged an exciting two-parter with an outstanding cast, skillfully moving between legend, historical drama, and adventure film. Walter Kärger, who already impressed with his script for the historical drama ‘Friedrich Freiherr von der Trenck – Zwei Herzen gegen die Krone’ (Friedrich Freiherr von der Trenck – Two Hearts Against the Crown), was responsible for the screenplay. Alexandre was also no stranger to lead actor Ken Duken, as the two had already worked together in 2000 on the adventure drama ‘Gran Paradiso – Das Abenteuer Mensch zu sein’ (Gran Paradiso – The Adventure of Being Human)."
