DFB confirmed in their press conference earlier that there will be a movie, titled "Die Mannschaft", coming to the cinema on November 10th and to TV in December. It's 90 minutes long. They will show the complete World Cup including the preparation, beginning with the training camp beforehand, spanning up to the reception in Berlin. They'll use their own and press materials as well as TV pictures from FIFA and the TV stations. But they'll also show self-filmed videos by the players, coaches and staff - especially the hours after the victory and the night of celebration. [Oh dear, we'll see a lot of funny drunks.]
There will be a photo book too, titled "Eine Nacht in Rio" (A Night in Rio).
(Bonus quote from the press conference: Manuel Neuer: "I can't give any prognosis regarding Lewandowski, but there have been whole training units when he didn't score against me.")
Tomorrow's press conference will feature Thomas Müller and Christoph Kramer. That should be fun.
ETA: They have a number of new videos up, including "Training impressions" which is mostly slow-motion scenes by someone who wishes they could have been a proper artistic editor. It does have very soulful looks of a drenched Mats Hummels for those who like that sort of thing.
