“In All Friendship’ fans irritated: ARD star hardly recognizable. ARD did not replace Karsten Kühn on “In aller Freunde”.
The actor first appeared as Jakob Heilmann in the series when he was nine years old. Since then he has appeared in episodes again and again, but has changed over the years. The child actor has become a grown man - one with a beard. It's this beard that's currently confusing fans so much.
