Just like in two previous films about Adam Miauczynski, director Marek Koterski considered casting Cezary Pazura in the lead role. However, he changed his mind because of the fact that Pazura was then associated too much with popular sitcoms, and although the film had many comic scenes, it was not a typical comedy anymore.
Adam Miauczynski is obsessed about the number seven. He does all his daily routines 7 times. When speaking to his mom, he says he is 49 years old, or 7 x 7. He lives at the Polaka street, number 7 (Polaka - means Pole street).
