If memory serves, there is no male nudity in NIGHTWATCH. However . . . .
If you ever see the original Danish version, it's probably got the longest (no pun intended) full-frontal male scene I've ever witnessed. Shocking stuff, seeing as how I'm an American and not used to such . . . lack of modesty, if you will. The first time I watched it, I found myself tilting my head and squinting, unsure if I was really seeing what I thought I was seeing (the first copy I owned was a bad, grainy bootleg). I couldn't believe it -- especially considering it's practically a close-up . . . .
Now I've probably got you ladies of the board dying to see this one. :)
