Since the only Dario Argento film I've seen that was released after the eighties was the gawd awful The Card Player (2004), and seeing how it's October and I am in a good mood, let's accentuate the positive. Here are a collection of posters for the Italian giallo/horror progenitor madman director from his gold era of 1970 through 1987.
The Bird With the Crystal Plumage (1970)
Cat O'Nine Tails (1971)
Four Flies on Grey Velvet (1971)
Deep Red (1975)
Tenebre (aka Unsane) (1982)
Phenomena (aka Creepers) (1985)
Opera (aka Terror at the Opera) (1987)
