At the International Film Festival of Rio de Janeiro (23 September to 7 October 2004), "Lost Zweig" — with Ruth Rieser in the female lead — attracted great interest from the press. What no non-Brazilian had managed in the previous 35 years, Ruth Rieser achieved at the Brasilia Film Festival in November 2003: By unanimous jury verdict she was named best actress of the festival and awarded the "Candango". The Candango is the most important prize in Brazilian cinema. Ruth Rieser impressed audiences and jury alike through her portrayal of Lotte Zweig in the Brazilian production, shot in English, "Lost Zweig". The film depicts the final weeks in the life of Austrian writer Stefan Zweig and his wife Lotte, who took their own lives in Brazilian exile in 1944.
