two things
First, Star Wars, is also known as Star Wars IV, so listing both and only treating one as the correct answer is just bad. Secondly, I haven't seen half those films, and a few I hadn't even heard of, so it doesn't do a lot of good to expect folks to have seen them. Admittedly, most of the mysterious ones are towards the end, but could you at least use movies that I've at least heard of?
