Other mistake: When the former pimp brings fresh flowers for Rosa's tomb, the gravestone says she died in 1972, but both the inspector and his colleague said on separate occasions that the murder happened 4 years before - and the movie is set in 1975 and at the exact same day of her death.

Other mistake: Legendary wrestler Antonino Rocca makes a cameo appearance in the movie. He is, as correctly listed in the closing credits, one of the "Funeral Attendants" together with Michael Weil. However in the opening credits he was specifically billed as the Funeral Director, which is Ronald Willoughby's role as correctly listed in the end credits. (00:00:50 - 01:45:15)
