I didn't know #10 because I must shamefully admit that even though I've seen the original, I've never seen the second or third (or fourth) parts. I also didn't know #4. The first bit made me wonder if it was part of that franchise, but I've never seen any of them and didn't even know the proper names of any sequels. The rest of my missing points are from parts of #5 and the bonus question. I knew the show for #5 but not the characters or the actors.

Neat quiz. I liked #9, I had to think about it for a moment and then it brought a smile to my face.
