Recently, I was reflecting on films the have profoundly changed or redefined how I watch movies and approach filmmaking. I thought it would be interesting to assemble a list of the films that have been of most impact for me. So here is a dozen films, and reason why. But being a person that has a hard time making lists of such things, I hesitate to call these the definitive top twelve movies that have changed me. The top six certainly have been of such deep and lasting impact to me that I feel confident in listing them in such high ranks, and have indicated in italics the prime reason I feel they have been of such formative influence on me as a film viewer and filmmaker. There are, of course, a vast number of notable films that did not make it on to this list. That is not to say I haven't found profound value in them. But I thought I would put this out here for discussion and further exploration.
