I mentioned this briefly in the chat last night, but I'll reiterate it here again. I suspect that a majority of filmspotters were tempted, by habit, taste or cinematic knowledge, to add more recent directors to their lists. Some of us do watch older movies, be them from the US or foreign, but a vast majority of message board members it seems to me are more familiar with directors such as Fincher, PTA and Nolan, just to name a few. That arguably explains why they earned such stunningly high positions in the list. If we all watched an equal amount of old/new and US based/foreign films, I very much doubt the top 100 list would look like the one we just created.
