In episode 7 of season 2, that aired on Showtime on Sunday November 11th 2012, Rupert Friend is in a hospital and suddenly drops his gown. We see his very nice and firm butt and for a couple of frames what appears to be a pretty big, white, uncut cock.
In this movie, Tom Hardy and Laurence Fox are both seen fully naked (frontal) as they are forced to take a shower after being captured. Both are uncut. Laurence Fox has a pretty big dick.
