I collect posters and have dozens of them hung around my apartment (most are original)... some of my favorites of recent years... Lost in Translation (1-sheet A/B [own both])
My favorite movie poster is the US version I have for The Big Blue. I have been searching for the french version that has the faces of Jacque and Joanna in the water for years now.
I also love the poster for the Mosquito Coast and the Emerald Forest.
