Seeing his seminal film The Seventh Seal changed the way I watched movies. It showed me, for the first time, that there could be more to a movie than just the image on the screen, indeed, that there SHOULD be more (it also introduced me to Max von Sydow!). This is a great loss to true cinema. On the other hand, maybe he died from the sheer sadness of seeing what passes for movie entertainment these days.
You will be missed and remembered, sir.
