Okay... So I was watching
The Empire Strikes Back, and I was reminded of something that I noticed the first time I saw it. It is a scene after Lando Calrissian has betrayed our heroes to Darth Vader. Han Solo is being tortured in some sparking device. While he is strapped to the device, before it closes, you can see a clear outline of his penis (pointing downward and to his right) through his pants.
After adoring Harrison Ford in countless movies with him always wearing loose fitting pants... this was quite the refreshing sight.
I can't be the only one that ever noticed this. I'm off to search for similar threads, and to see if I can figure out how to get a screen cap posted.
