I've only seen 13 (and only 5 of the top 10). I'm pretty sure I can at least double that number in the next couple of weeks - Hulu+ has a number of the titles and I actually have a few sitting on my shelf that I haven't got around to watching yet (Metropolis, The General, Seven Samurai, a few more...) Kind of embarrassed by the low number, especially since I haven't even seen a number of the American ones (Mulholland, Singing in the Rain, Some Like it Hot).
