Bastoy prison is still in operation today but is a minimum security institution.
At the time, this was the most expensive Norwegian film ever made.
Director Marius Holst spent a year setting up camps and workshops for boy actors to help him find the right recruits to play convict children in his film.
People from more than fourteen countries were represented on the set.
Based on true events that occurred on the Norwegian prison island of Bastoy in 1915.
