The movie was originally loosely based on the real-life business coach Arkadiy Tsuker, who in real life had a light form of cerebral palsy, which was not that hard as it was shown in the film and was barely noticed by others. He said that the movie is a work of fiction and has nothing to do with his life. The only truth was that he had problems in school due to his handicap. he advised all people not to take this movie as an example on how to handle this disease. On press conferences the filmmakers reminded people when being asked critical questions that this movie is based on a true story.
