NACH DEM STURM (After The Storm)
Director: Gustav Ucicky, whom also directed the cult classic The Bicycle Thief
The film Salzburg, summer 1945. US Major Sinclair, requisitions the villa of
Baron von Tretini, an Austrian politician who had fallen victim to the Nazis. The
baron’s daughter, Barbara, a virtuoso pianist, shaken from years spent in a Hitler
workcamp, tries to resume her pre-war profession and form an orchestra. But her
state of exhaustion has made her health precarious. Attracted by Barbara, Sinclair
arranges a convalescent stay in Ticino where the two decide to marry. Meanwhile, a
convoy of prisoners bring back Michael, Barbara’s ex-boyfriend, a composer
everyone thought had died. Emaciated, all alone in the world, and with no
resources, his hands ruined by frost-bite, Michael’s only possession is a piano
concerto he composed specially for BarbaraÉ Nach dem Sturm is a Swiss-Austrian
co-production, whose exteriors were filmed partly in Ticino, in Ascona and on San
Salvatore during the summer of 1948 by filmmaker Gustav Ucicky. It was an
adaptation from a short story by anti-Nazi German writer Carl Zuckmayer
(1896-1977) Ñ published a year after the film’s release. The film was financed by
Willy Wachtl, a Tyrolean who moved to Berne, and was also owner of the biggest
cinema chain in Switzerland. Nach dem Sturm was an enormous success in
Germany where crowds wept “tears over the dilemma of an aristocratic pianist torn
between the handsome major from the occupying forces and the fiancé believed
dead, a former soldier fighting for the Wehrmacht and escapee from prison camp”
(Hervé Dumont). The only extant materiel relating to this film was discovered at
the Archives du Film du Centre national de la Cinématographie in Bois d’Arcy: a
nitrate dupe 35mm from the original German-language version which lacked only
the 9th reel, and various French dubbed nitrate prints. A safety acetate print was
then made from the original, but with the ending in French.
