In the film, there is a concert in which the fictional Oi-group "Roimkommando" (the real life punk band "Smegma") holds a concert, to which Oi-skins led by Koma (Goerts) violently mosh to. On the DVD commentary track, the Redings explain that they could not use the sexually charged word "Smegma" in a film which was meant to be seen by teenagers, so they had to change the name of the band. In addition, all the Oi skinhead extras were real Oi skinheads, who demanded beer as compensation when they slowly grew weary of filming. In addition, they moshed so hard that Goerts was often knocked out of the middle and the scene had to be reshot.
