Shot in a 2,35;1 aspect ratio, it was never released on home video that way. Only in 1,85;1.
Alexandra Neldel, Rhea Harder and Simone Hanselmann worked together on Gute Zeiten, schlechte Zeiten (1992).
The cars in the movie have licence plates which start with TMG. This stands for "Tele München Gruppe", owner of the films production company (normally, the first part of the plate shows in which city or municipality the car is registered).
The film shown at the cinema is Relic - L'evoluzione del terrore (1997), also distributed in Germany by TMG. The crowd clearly features some boys aged 12-14. In theory this would be a punishable violation of the youth protection laws since that film has an age restriction of 16.
