The film was selected as the Belgian entry for Best International Feature Film at the 94th Academy Awards.
No music score during the ending credits.
A novel of the same name about bullying and written by 50 Cent predates the movie by a decade. The movie is loosely based on the background to the tragic murder of James Bulger in the UK almost three decades earlier.
