No Need For Time Travel: October 21st, 2015 is 'Back to the Future' Day

The day Marty, Jennifer and Doc Brown travel to in the future in 'Back to the Future, Part II'

Back to the Future, Part II

It's been nearly 30 years since Marty McFly, Jennifer, and Doctor Emmett Brown traveled to the then far-flung future date of October 21st, 2015, in Back the to Future, Part II, but viewers have eagerly awaited for the trio's arrival. The flick went to become a huge hit at the box office and more importantly, a classic among sci-fi film fans, for its zany portrayal of the paradoxes of time travel between 1955, 1985 and 2015. And social media users shared their excitement about finally reaching today without a time machine by tagging posts with #BTTFDay.

Fans recreated and quoted some of their favorite moments from the trilogy

Several brands are mentioned in Back to the Future, Part II, and many of them are embracing the products seen in the film's version of 2015. At this year's New York Comic Con, Pepsi announced they would make a special edition "Pepsi Perfect," the soft drink Marty drinks in a 2015 diner. It's available online exclusively at Walmart and Amazon until supplies run out.

When Marty first arrives in 2015, he is scared by a holographic shark promoting Jaws 19. Universal Pictures made a real trailer for that movie (which exclusively lists its predecessors) just for today.

Marty also puts on a self-lacing Nike shoe, which the Michael J. Fox Organization announced will be sold in 2016, but if you can't wait you can make a pair yourself.

Without a doubt, the franchise's most iconic product is its time-traveling DeLorean. Though the DeLorean Motor Company went defunct in 1982 (before the first film even came out), ride-sharing app Lyft teamed up with Verizon and will send out a fleet of DeLoreans to pick up passengers in New York City tomorrow, October 21, 2015.

Michael J. Fox even used the opportunity to make a statement through the White House about research the Michael J. Fox Foundation is doing, which read:

We’ve come a long way since 1985.

When Marty McFly and Doc Brown traveled 30 years into the future, we could only imagine the innovations we take for granted today -- new ideas and technologies that have completely changed the way we live, learn, and work.

Back then, if you’d have told me that I’d go from talking on a cell phone to talking cell biology, I would never have believed you. But today, The Michael J. Fox Foundation is helping to spearhead research collaborations to speed a future in which we can treat, cure, and even prevent brain diseases like Parkinson's.

So what’s possible in another 30 years? Call me an optimist, but I believe that by 2045 we’ll find the cures we seek -- especially because of all the smart, passionate people working to make it happen. Doctors and researchers around the world are developing new tools to improve the diagnosis and treatment of brain diseases, to tailor treatments -- for all illnesses -- through precision medicine, and to make life better for millions of people. This truly is the stuff of the future.

Today, on “Back to the Future Day,” I challenge you to imagine the world you want to live in thirty years from now. The White House is hosting a series of online conversations with innovators across the country all day long. Check it out and add your voice here.

We can't all be brain scientists, but all of us can get involved. One reason Parkinson’s research has come so far in the past 15 years is that people and families living with the disease have stepped up as advocates and innovators themselves, working to build the future we all want.

Together, we’ll make neurological illness a thing of the past.

And if we all eventually get hoverboards, well -- that's a bonus.

--Michael J. Fox
