However, Kotopouli herself recognized Lambeti's talent and hired her. She adopted the professional surname Lambeti and became a lead actress. She starred in Hanneles Himmelfahrt by Hauptmann. In 1945, she met Marios Ploritis, her future husband, during the filming one of her first films, Adoulotoi sklavoi (1946).
