Filming
It was filmed in Minsk, Belarus for 7 months. The school hallway scenes were filmed at school number 115 and the episode when Mishka tells Dennis what he loves and when Ljovka gives Dennis a sleeve was filmed at school 122 in Minsk. The classroom scenes were filmed in the studio.The train scenes were filmed on an inoperative railway line in the Smolevichi region. The train consisted of a locomotive and three carriages. The tower that Dennis was afraid to jump from was filmed in Smolevchi. Vladimir's regular dark blond hair was painted with hydrogen peroxide which caused it to become a lighter shade of blond in the film. During the scenes where Dennis cries, Vladimir said that "glycerin was instilled on the set. The eyes immediately began to pinch, and tears appeared. True, once they were real. The director took the football tickets away from me, and I cried with resentment. The stage was filmed and the tickets were given to me." Georgy fondly recalls that "The assistants came to school and took me out of school, it was such happiness!". Vladimir Stankevich said that Georgy,"stuttered for real, and they wanted him to take a stunt double for voice acting, but when he tried to voice himself, he stuttered exactly in the same places as during the filming."
