Maske in Blau
Maske in Blau (Mask in Blue) is a grand operetta in two parts (six scenes) with music by Fred Raymond to a libretto by Heinz Hentschke and Günther Schwenn. The work had its premiere under Werner Schmidt-Boelke on 27 September 1937 at the Metropol Theater in Berlin. It was revived on 20 March 1955 at the Théâtre Municipal, Strasbourg, under the title Le masque bleu.
It was made into a 1943 film directed by Paul Martin. A decade later Georg Jacoby remade the film as a vehicle for his wife Marika Rökk.
