Try our 'Back to the Future' quiz

(CNN)Happy #FutureDay!

As you may remember from "Back to the Future Part II," Marty McFly travels forward in time to October 21, 2015 to save his children. Twenty-six years after that 1989 movie hit theaters, that day is finally here.
To celebrate, AMC, Regal and other North American theater chains will screen the trilogy Wednesday (AMC at 4:29 p.m. local time, the time Marty arrived). The movie trilogy is being re-released on Blu-ray, and Pepsi is selling specially labeled bottles of "Pepsi Perfect," the cola McFly orders in the second film.
(Good luck getting your hands on a Pepsi Perfect, though -- they were mostly sold out.)
And we offer this trivia quiz.
"Back to the "Future's" predictions about what life would be like in 2015 were part right (big-screen TVs!) and part wrong (hoverboards). We're still not sure about the Chicago Cubs winning the World Series, but right now it's not looking good.
Maybe you can score better on our quiz. Think, McFly, think!
