-- Great Scott!
When Marty McFly was sent 30 years into the future as part of the plot in "Back to the Future Part II," he arrived in a time when where there were hoverboards zipping around, people wore self-lacing shoes and flying cars were the norm.
The date? It was Oct. 21, 2015.
Sure, there was a lot of the film got wrong about 2015 - but there are some things it got right too.
Let's take a look:
Right On, McFly:
1. Flat screen televisions, Skype-like communication and card readers
"Nobody calls me 'chicken,' Needles," an older McFly says to Douglas Needles via a screen before scanning a card remotely. "Nobody."
While people are identified when their eyes are scanned in the film and other biometric technology, today people can use their fingerprints to unlock their iPhones or check into a 24 Hour Fitness gym.
3. 3-D Tech
In the film, Marty McFly gets a fright on the street by a 3-D "hologram" of "Jaws 19."
1. Flying cars, Hovercraft
In the "Jaws 19" scene, McFly sees an ad for Wilson Hover Conversion Systems in which "now you don't have to worry about traffic" with "skyway flyers" for $39,999.95.
We don't have quite the same hovercraft today and even in the movie, they had limitations: "Hey McFly, you bojo, those boards don't work on water!"
But in August, Lexus said it's testing its own prototype Hoverboard that works over a magnetic track.
2. Self-lacing Shoes
The 5-year old in us still wishes for this.
Last year, Nike shoe designer Tinker Hatfield said he hoped self-tying sneakers might one day become a reality.
3. Fax machines, phone booths
Though fax machines and phone booths seem to be widely used in McFly's future, cell phones and email have all but replaced their use today.
