Rosenmüller is famous for his bavarian films - he comes from upper bavaria and as I am not a film fan the first time I heard about him was a Playboy interview in which he and Thomas Müller in July 2013 in which both were questioned about values, homeland, roots, family... Funnily a film about a Mancunian hero with Northern German roots is done by a Bavarian cult film director - a big Bayern Munich fan - and the film is partly financed with 2 Mio. EUR by the FilmTVFonds Bavaria in which the state Bavaria has big shares.
Rosenmüller was in Bavarian TV tonight talking about the film - in Germany it starts mid of March. He "found" the material for the film and wanted to make it since then about 10 years ago - had long talks with Trautmann in Valencia?, where Trautmann lived the recent years.
The stadium scenes of Wembley werde done in the Rosenaustadium in Augsburg - the former stadium of Bundesliga club FC Augsburg who have a new stadium since 2014. Some scenes are filmed in Munich, some in Manchester.
