25 Days of Gays: Brotherhood (2009)

The Danish film Brotherhood tells the story of Lars (played by Thure Lindhardt), an ousted gay serviceman who takes an interest in a neo-Nazi group. His training pairs him with Jimmy (played by David Dencik), another former military man with anti-gay tendencies. The two begin on hostile terms but their seclusion together leads to friendship and ultimately passion until their coupling is discovered. There's rear nudity from both actors and frontal nudity from David during a shower scene. There's also rear nudity from Morten Holst, Jon Lange, Martin Metz, Johannes Lassen and Mads Rømer as they enjoy some downtime on the beach.
