I don't think those nude pics are really GM. Just like the one posted of Tab Hunter are not him.
Rory Calhoun was ex con trash before Willson got his hands (ahem) on him, but hot looking nonetheless. Boy-oh-boy did he clean up good! Imagine wholesome Guy Madison getting pounded by rough trade Rory!

I suggest you watch the film "Till The End Of Time", starring Guy Madison & Robert Mitchum, he really was beautiful in that film. It is difficult to find, but worth the search if you want to see G M at his best.
