Profile Unusual

Army Doctor

Brief butt crack being examined by the army doctor. He was in his early 40's and thinner here than his nude scene in the Virgin Spring.
Fair warning: movie has some unexpected violent scenes and animal slaughter. (amazingly, with a PG rating)

Public Baths

Feore is looking very fit in his early 50's, and the scene features him escaping a public bath after a failed assassination. He is wearing a sheer wet loincloth and as he is turning away reveals a see-thru frontal.
The way the fabric drapes and the lighting make him look sizeable, but
given his long career and next to no nudity in the past, it is entirely possible he is wearing a prosthetic. Either way, he's looking handsome here and if it is all him he's certainly got nothing to be ashamed of.

On top

Side view of boob/nipple during sex scene with Skarsgard

Multiple

Several views of buttcrack during multiple sex scenes, and quick side view/frontal taking off robe.

Butt crack

Very brief butt crack in bed with Jane Alexander

Wet shirt bathing

Perky in a wet semi transparent shirt. Not bad for PG rating.

Hot Springs

Ambushed while bathing in the hot springs. Medium distance view of his hip and very brief butt crack stepping out of the water.

Shower Scene

French film from the early 80's. Brief full frontal exiting shower. (Water must of been cold.)

Moon

Drops his pants to moon someone through a window.

Multiple

Multiple butt crack scenes. Rob is not exactly an attractive looking guy.

Brief flash

Very quick view of butt crack getting into hot tub. Shot from from above, medium distance.

"Lost bet" scene

Brief butt crack when he falls over on top of Rob Corddry.

Two scenes

Viggo has two swimming scenes where you see his butt crack. The character is starving and he does not look healthy at all in the scenes, although apparently he has enough strength to swim out to a wrecked ship in the wind and ocean waves.

Hallway

Butt crack and a dark frontal (don't really see anything) as he turns around. He was very skinny at this point in his career.

The movie is godawful.

Shower

Stumbling drunk in and out of shower. Blink and you'll miss it view of butt crack and frontal.

shower

Heston was clearly nude on the set, but all video copies frame out any nudity. Unless you have access to a 35mm print to frame the picture how you want, don't bother seeking this one out if you're only watching it to catch a glimpse of his wobbler.

body double

There's a very brief frontal shot of his character, but if you look, the tattoos are different, and the actor's hair color is darker. In the absence of a clearer shot with his face i'm calling this one a body double.

beach

romping on the beach with faye dunaway. Several split second views of his hips and buttcrack. Should get bonus points for the pornstar stache he wears in the scene though.

Older actor in boring drama

British television movie. Very brief frontal exposure (seen from the side) as he is stepping into the bathtub. He is largely blocked by the actress in the scene so the exposure may have been unintentional.

Sniper

This might be the most played nude scene in history, given the millions of times this show has played in reruns. Burghoff dashes back and forth to avoid a sniper while he's wearing a towel, then runs back into the shower tent and loses the towel on the way in, for a split second view of his buttcrack.
