The scenes with Nora Tschirner and Jürgen Vogel on the red carpet at the German Film Awards were shot during the actual red carpet ceremony in 2007.
All four of Til Schweiger's children can be seen in the film: son Valentin Schweiger plays the young Ludo, eldest daughter Luna Schweiger plays the young Anna, daughter Lilli Schweiger plays the girl with the cap and youngest daughter Emma Schweiger plays Cheyenne-Blue.
After protests from parents and politicians concerning some dialogue scenes, in January 2008 the FSK raised the rating from "Not under 6" to "Not under 12" (which actually does NOT avert children between 6 and 12 to see the film, they must just be accompanied by a parent or legal guardian).
The name Chayenne-Blue (one of the children appearing in the film) alludes to the names of German actor's Uwe Ochsenknecht's children Jimi-Blue and Chayenne Ochsenknecht.
Ludo bullied Anna when both of them were kids, which implies they are roughly the same age. In real life, Til Schweiger is nearly eighteen years older than Nora Tschirner.
