58. Denis Podalydès in Les Damnés (2016)

Age: 53

I love nudity in theater, but this actor showed literally ALL. You can see him from every side. And thankfully, there's a recording in HD. Simply amazing!

52. Philipp Hochmair in Das Sacher. In bester Gesellschaft (2016)

A short flash of penis. He did more naked scenes in TV and theater.

50. Ramon Esquinas in Vis a vis (2016)

Age: 47

Short frontal, but he's a handsome man with nice body.

45. Viggo Mortensen in Captain Fantastic (2016)

Wow, I can't belive that he's almost sixty in this scene, very nice body! He likes to show it.

28. Łukasz Simlat in Zjednoczone stany miłości (2016) [1]

3. Thomas Loibl in Toni Erdmann (2016)

Great full frontal scene! You can clearly see everything in high resolution!
