Submarino (2010)
Submarino is a 2010 Danish drama film directed by Thomas Vinterberg, starring Jakob Cedergren and Peter Plaugborg. It is based on the 2007 novel Submarino by Jonas T. Bengtsson, and focuses on two brothers on the bottom of Danish society, with lives marked by violence and drug addiction. The film was produced by Nimbus Film. As a condition from the financier TV 2, half of the cast and crew were novices, which the director enjoyed as it gave an experience similar to his earliest films.
