I think I've seen this trailer for Harry Potter and the Half-Blood Prince that they were advertising on the Hulu home page, but I was curious about the ability to embed a live stream. So let's see how this works, shall we?
One thing I didn't realize was that the movies shown on Hulu often expire after a time, so early films like Sideways are gone. Instead, there are a lot of movie trailers. But there are still some interesting ones: if you haven't seen Super Size Me, it's entertaining and alarming. Here are some others that are somehow significant, though in an "eat your broccoli" kind of way.
