IMDB List is Incomplete

As much as I love this new feature, it seems to be missing quite a few movies. For instance, there's at least 11 foreign movies missing that can be streamed on Netflix in the USA that should be on the IMDB list. Among the missing titles: Once Upon a Time in America, Life is Beautiful, Cinema Paradiso, Bicycle Thieves, Metropolis, Oldboy, Downfall, 8 1/2, The Artist, IP Man, In the Name of the Father,
