Back to the Future or Harry Potter and the Goblet of Fire?

Are you a fan of Harry Potter and the Goblet of Fire? Of Back to the Future as well? Prove it! Select which quote belongs to which movie and see how good you are:

- We better back up. We don't have enough road to get up to 88.

- Roads? Where we're going, we don't need roads.

Dark and difficult times lie ahead. Soon we must all face the choice between what is right and what is easy.

If you want to know what a man's like, take a good look at how he treats his inferiors, not his equals.

- 1.21 gigawatts! 1.21 gigawatts. Great Scott!

- What-what the hell is a gigawatt?

I want you to look at me when I kill you! I want to see the light leave your eyes!

If my calculations are correct, when this baby hits 88 miles per hour... you're gonna see some serious shit.
