So, fellow letterboxders... please add suggestions! :-)
It's worth mentioning perhaps, that not all of these are to be considered great cinema. I tried to add those, that for one reason or another, created some kind of buzz when they came out. Mostly positive buzz, I guess, don't want to add complete failures here.
And hopefully, some classic decent films as well.
