One of the props used in the film - a box of dirty magazines called "Peach" - had to be looked after for particularly carefully due to the increased attention it was getting. But still, as the shooting locations changed, the box disappeared one day. It was returned the following day with the magazines clearly having experienced some wear and tear.
During the making of the film, the joke "in your pants" became very popular among the crew as a response to any occurrence. Eventually, some of the "in your pants" jokes even made it into the actual film even though originally they were not part of the script.
5 liters of fake blood (not to mention all the blood, sweat and tears of the entire cast and crew) were used during the making of the film. However, this was not enough, so in some scenes beetroot juice and raspberry jam was used as well. Actor Andris Daugavins, who plays Harry Kucharyonok, particularly hated the jam - if jam was used, he would constantly be surrounded by flies and once, when he was taking off his trousers, the hair on his right leg was accidentally waxed off because of the jam.
The title of the film remains as it was originally conceived while the script was being written. But during the making of the film, one other option was considered as well - "Mastermind", which is also the title of the crime series that Imant Veide, the main character in the film, is writing. But in the end, "The Foundation of Criminal Excellence" prevailed.
There was only one clapper board used during the making of the entire film. On the first day of shooting, one of the camera operators Kaspars Cirsis wrote the film's title on the clapper board with a red felt-tip pen, and the same one was used for the entire shoot. On average, someone would drop the clapper board every three days, but it never broke.
