Swedish actress, born in Sundsvall on July 31, 1944. She always dreamed of being an actress and after landing a small role in an Italian film, she ended up living and working in Italy, playing uncredited roles in many films during the 1970s and 80s.

For many years, she lived with a director named Roberto Carnicci, who was friends with Fellini, and Catharina was able to get small roles in four of Fellini's films: Satyricon (1969), Roma (1972), Amarcord (1973) and La città delle donne (1980). Amidst her many small roles, she also had quite a few speaking parts, such as in Delitto sull'autostrada (1982), where she's jokingly seduced by Tomas Milian who asks her: «Do you have a license for these pair of eyes?».

Catharina moved back to Sweden in 1983 and began to work with astrology. She also studied to be a healer and has continued her acting career by appearing in some films by Swedish director Lars Mohlin.
