During her acting studies she already gained notice and received widespread recognition for her enchanting but self-confident impersonations of the princess roles in German classic theatrical motion pictures in the early 1960s based on historical fairy tales,[3][4] like Mother Holly (1963), The Golden Goose (1964) and King Thrushbeard (1965) co-starring German cult actor Manfred Krug.
[6] In early science fiction motion pictures like Signale – Ein Weltraumabenteuer (1970) (English: "Signals") and in historical feature films like the spy thriller The Invisible Visor (1973) which has already achieved cult status, co-starring the young Armin Mueller-Stahl, or as the malicious white farmers daughter in the German film version of the American Indian legend story Osceola (1971) or even in first episodes of the German TV classic crime series Police call 110, where she appears as one of the first officiating female police detectives and inspectors besides the actress Sigrid Göhler in German TV, she has so much the more astounded and irritated her fan base knowing her from the princess roles by showing completely different faces in the 1970s and exposing as character actress of complex parts.
Already during her first film work she fell in love with theater, especially the experimental and political theatre, which was able to change something in the time of upheaval in Germany.
The actress, who has frequently campaigned for art and culture support and development in Germany in the last decades and has carried a yearly exhibition festival with her husband to support artists in this area, became a talking point recently again by participating in a supporting role as mother of the lead in Samuel Maoz's latest international motion picture Foxtrot (Israel, 2017), a sequel of his award-winning motion picture Lebanon (2009), which will likely screen in Cannes and won the Silver lion (Grand Prix de Jury) at the Biennale 2017/18.
The parents of the Brasch brothers were Jewish immigrants to the UK in the late 1930s during the pogrom in Germany and moved back to Germany after the end of Second World War, which made both authors, Thomas and Peter, being strongly driven by the dream for eternal peace and freedom of thought in their work, a common ground between the Braschs and Karin Ugowski.
Peter Brasch had a crash on Karin Ugowski and has dedicated a book of poetry to her (inscription) and wrote another radio play called The Golden Goose – an audio drama adaptation in 1989[16] inspired by her role of princess Roswitha in the classic movie.
