In an interview in Volle Kanne (ZDF) Hardy Krüger Jr. stated he had also completed training as a chef[citation needed].
After graduating in 1991 he began his career in Germany with an appearance in the ARD series Nicht von schlechten Eltern and with the lead role in Gegen den Wind.
In May 2006 he first appeared as the replacement for Christian Wolff in ZDF's Forsthaus Falkenau, in which he played the lead role of the forester Stefan Leitner.
In 2009 he remarried to Austrian communications trainer and painter Katrin Fehringer, with whom he lived in Starnberg near Munich and with whom he adopted a girl from Thailand in 2009.
