As the film is mainly told from a child's point of view, director Gabriele Salvatores instructed his director of photography Italo Petriccione to shoot most of the film at a child's height.
This film was loosely based on a true story of a kidnapped boy from Milan and the novella written about the incident.
Salvatores interviewed nearly 600 boys for the part of Michele, ultimately settling for novice Giuseppe Cristiano, the son of a Fiat car worker.
The film takes place in 1978.
