There is no more decadent and handsome a man. I recommend you see him in the Fellini short “Toby Dammit” in Spirits of the Dead (1968). The movie did not make my Picks (the first two segments are too boring to be honest), but I still think it is worth a look. Not only for devilish hunk Stamp, but some visually stunning cinematography in all three short movies.
You can also see Jane Fonda dress how I would if I were insane.
