Soccer player Mehmet Scholl is repeatedly referenced in the movie's dialogue, posters in the movie and as a player in a soccer video game that the two protagonists play.
The movie is not allowed to be aired on TV on Good Friday (Karfreitag) in Germany, since it's an important public holiday for catholics and evangelicals. Both churches consider this movie as insulting.
The plot was modeled after Reservoir Dogs - Wilde Hunde (1992). However, "Lammbock" establishes who the undercover cop is immediately, and the main characters' plan involves a crop of marijuana, not a bank robbery.
The original film location of the pizzeria is in Cologne, where it is still existing. The university scenes were shot at the Technical University of Cologne.
