After acting studies at the Gothenburg City Theatre from 1950-52, she made her breakthrough debut in Gustaf Molander's Kärlek (1952). When Ingmar Bergman became head of the Malmö City Theatre he asked her to join him there and with him as a director she played the role of Margareta in Goethe's 'Faust'. Bergman also gave her supporting roles in his movies, most notably the mute woman in The Seventh Seal (1957). She followed up on a few offers from abroad but the roles wasted her screen presence. Bergman once again gave her an offer she couldn't refuse, to direct a movie. Paradistorg (1977) received a lot of praise from all over the world. Time Magazine considered it one of the four best non-US movies of 1978. Her appearances in movies has been rare but she gave a wonderful appearance in the children's TV show Kaspar i Nudådalen (2001). Lindblom has for many years worked for The Royal Dramatic Theatre, appearing in plays by August Strindberg or William Shakespeare. In 2002 she received a Guldbagge award for her lifetime achievements in movies.
