You have a small error in your answer key. Michael J. Fox played Marty McFly, not George. George McFly was the father. So you'd better make like a tree ... and correct it.

Your second Aliens one got me. I wasn't sure what it was, but at first glance I thought, y'know, that could be Aliens, even though I don't know who said it. But you'd already had Aliens earlier, so I wrote it off and moved on.
