Theresa Vilsmaier (born June 8, 1989, in Munich) is a former German film actress who now works as a physician. She is the daughter of Czech actress Dana Vávrová and German director Joseph Vilsmaier. Her sisters, Janina Vilsmaier and Josefina Vilsmaier, also work as actresses. Vilsmaier grew up multilingual and attended the Bavarian International School in Haimhausen. In the autumn of 2008, she began studying law in London. However, due to her mother's battle with cancer, she returned to Germany after her first semester. Following her mother's death, she changed her field of study and began medical school at Ludwig-Maximilians-Universität Munich (LMU). On February 9, 2011, she passed her First State Examination. She completed her studies with a doctorate and has been working as a physician at the Hormone and Fertility Center at the LMU since 2019. Together with her older sister Janina, she serves on the Board of Trustees of the Dana Vávrová Foundation, which was established in 2010 to fight cancer. Theresa had her very first "film role" at the moment of her birth, when she was filmed by her father. This birth scene was later used in the film *Rama dama*. She appeared in other films by her parents—for instance, in *Marlene* as Marlene Dietrich's daughter, Maria, and in the children's film *Der Bär ist los!*. She held further roles in the films *Bibi Blocksberg* and *Das fliegende Klassenzimmer*.
