Back to the Future or Jackie Brown?

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

- 1.21 gigawatts! 1.21 gigawatts. Great Scott!

- What-what the hell is a gigawatt?

Here we go. AK-47. The very best there is. When you absolutely, positively got to kill every motherfucker in the room, accept no substitutes.

- 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.

Half a million dollars will always be missed.

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

What the fuck happened to you, man? Shit, your ass used to be beautiful!
