Submarine

Submarine is a British dramedy released in 2010. It's the coming-of-age story of Oliver Tate, a teenage boy living in Swansea, Wales in the 1980s. He falls in love with Jordana, a fellow school student and committed mischef-maker, and at the same time starts to worry about his parents' health and marriage.

It's based on the 2008 novel of the same name by Joe Dunthorne, and was the directorial debut of Richard Ayoade.
