Poll: Classics With Zero Accolades

All these movies are classics that, throughout the years, gained in popularity and cinematic stature. Today, on IMDb, they're rated at least 7.5 with more than 10.000 votes. Yet, at the time of their release, even a delayed time, these movies were strangely overlooked by the Oscars or any other festival or critics' circle or journalists' association. In other words, these movies were nominated for nothing. For which of these classics, do you find the absence of nominations the most surprising, if not unbelievable? After voting, you might discuss the list here (of course, these movies became so popular they were later selected to National Film Registry and were nominated for some DVD-related awards, needless to say that these nominations don't count)
