Because I have no idea what any of it has to do with anything yet I still think it is visually stunning and if it were a painting it would be hailed as some defining work of art. And considering it's a Jodorowsky film, which means copious amounts of drugs are in order, I imagine this poster is exactly the sort of image to sell The Holy Mountain on.
