In the scene where Hein (Benno Fürmann) tries to hide the corpse of Phil (Holger Speckhahn) there are two assistants appearing. The dark-haired one, who is constantly cursing (Martin Pölcher) actually is now (2006) assistant medical director at the Institute for Gynecology at the University of Bonn, Germany.
The door that leads to the stainless steel morgue room in the movie actually leads to the cafeteria of Technische Universität München. The movie was screened in the big wooden lecture auditorium seen in the movie, leading to a "picture-in-picture"-effect for the audience.
The models used in the film were inspired by Dr. Gunther von Hagens popular exhibition "Body Works" in which real cadavers are plasticized after being dissected. One character even mentions this process when we see the hall for the first time at the beginning of the film, but no real cadavers were used as the director thought it "too macabre". The models were created by a team headed by Joachim Grüninger and Birger Laube. The models were so accurate and detailed that the film's medical advisers thought they could be used as actual teaching specimens.
