Many people often lament the fact that it is almost 2015, the year that Marty McFly (Michael J. Fox) visits in 1989’s classic Back to the Future Part II, and we’re still no closer to getting our very own hoverboards. There was that one time when the Internet exploded all over the place thinking they were on the way, but as you’ll remember that turned out to be a hoax, of course. And while we’re not going to be able to step on a real Mattel brand hover board anytime soon, you can get pretty close, assuming you have a spare 15-grand.

Marty’s actual hoverboard from Back to the Future 2 will be up for auction. Yes, the actual prop from the film will be available for you to drop all of your hard-earned dollars on this October from Propstore, and the estimated asking price is 15,000 pounds. That may sound like a lot of money, and it certainly is for most of us, but you have to remember that this is the board that Marty swipes from that kid to outrun Griff Tannen (Thomas F. Wilson), the future son of familiar jackass Biff Tannen—all fathers and sons should have rhyming names. Just remember, don’t ride it over water, it doesn’t work very well when you do that.

In 1989 Back to the Future II showed us a vision of a not-too-distant future where the world had become a strange place where things hover off of the ground much more often than they do in our own time. That particular imagining of the future is almost upon us—Michael J. Fox’s Marty McFly flies his DeLorean into October of 2015—and because our sort obsess over this sort of thing, we keep comparing the reality of the film to the reality of our reality, to see how the two stack up against each other. This new inforgraphic does the same thing, listing out some of the inventions that the movie shows, and seeing which of those have come to pass over the last 25 years.

In this image, which popped up on T-shirts.com, Doc Brown (Christopher Lloyd) himself—sort of—guides you through items that have and have not materialized since Robert Zemeckis’ second time going back to the…you get it. How prescient was the film? Like most predictions, it was way, way off about some things, but it did manage to hit the mark on a few. Overall it’s batting about .500, which, given the circumstances, isn’t bad. There’s still one still left to happen, and a couple inventions even Hollywood didn’t see coming.

In 1989, Back to the Future II showed us a great many things that we should expect in the coming years. While we’re not quite to the 2015 we saw in the movie, 2014 is pretty damn close, but most of the things that we saw in that movie still haven’t materialized. We may not get hoverboards by the deadline, but there’s a hover-bike in the works, which is close. One area that we’re pretty far off is in the Jaws department. You may remember that Michael J. Fox’s Marty McFly sees and ad for Jaws 19. At the current count, there are only four Jaws in existence. One intrepid blogger, however, wants to rectify this situation. If movies lie to us, what else do we have?

Tumblrer Ctrayn has issued a challenge to the Internet, or more accurately, a call to arms to nerds and budding filmmakers across the World Wide Web. He seems to think that, collectively, we can crank out another 15 Jaws sequels in a year, in order to remedy this “enormous travesty.” Actually, we even have way more time than that. Marty doesn’t arrive in the future until October 21, 2015, so we have more than a year and a half to complete this task, should we choose to accept it. That’s less than one unofficial Jaws sequel a month. They don’t all have to be good, but I will still watch every single one of them.

With only a year and a half until we reach the future world of 2015 from Back to the Future Part II, many manufacturers and companies are racing to make that future a reality. Last year, Nike released the very limited edition McFly sneakers (without the power laces) and Mattel sold the limited edition pink hoverboard (without hover capabilities). It’s only a matter of time before the Pepsi Corporation releases the Pepsi Perfect soft drink (which won’t be perfect) and Pizza Hut starts selling hydrating mini-pizzas (which won’t hydrate). Now one online retailer is starting to sell limited edition Grays Sports Almanac iPad covers.

Great Scott! According to Back to the Future Part II, it will only be three more years until hoverboards are a reality. But for those who don’t want to wait that long, Mattel is currently selling non-working hoverboard replicas that look and feel exactly like the ones Marty McFly used in Back to the Future Part II. Check out a video review below…

In 1989, Back to the Future Part II was released in theaters, to the delight of sci-fi geeks and general audiences across the country. BTTF II would feature the fictional city of Hill Valley, California 30 years into the future, in the year 2015. To help create the futuristic Hill Valley, director Robert Zemeckis turned to a long-time collaborator, special effects supervisor Michael Lantieri.

In a new interview, Lantieri took a break from working with Zemeckis on the film Flight to discuss how they made hover boards and the flying DeLorean.

It would be much easier today, we had to fly around on piano wire old school and had to hide it. A lot of help from director of photography Dean Cundey and production designer Rick Carter. Designs of the sets with lines and things like that to blend wire. Basically everything was done live action. A simple one was out over the water, the board was just on a piece of mirror that was sitting out there with Michael standing there hovering over the water, it was just reflecting the water.

The hoverboard sequences in BTTF II are really effective. Even to a modern audience, the scenes are believable and exciting. Lantieri and his team are responsible for generations of kids (and adults) wanting their very own hover boards. Even though the film is 23 years old, the special effects are not dated in the slightest, even though they are practically made instead of CGI.

One of the best sequences in the entire BTTF trilogy is the locomotive pushing the DeLorean time machine at the end of BTTF III. This sequence contained a lot of special effects considering it involved a train engine, a DeLorean on train tracks, a hoverboard, and a thrilling rescue. Lantieri explains how difficult it was to bring these elements together for an exciting and memorable action sequence:

One of the things that was a huge huge concern of mine was the DeLorean in front of the train popping a wheelie. I was really afraid of not so much the car but a person in it with the train shoving it. Should something go wrong that train it will go right over top of the car. It was a really dangerous stunt to do. I talked Zemeckis into shooting that scene backwards. It was all in reverse, even to the point we had the hover board on little safety wires that would jiggle it and Michael picked it up pulled it into the car instead of throwing it out.

The Back to the Future Trilogy is one of the best movie trilogies of all-time. It continues to capture the imaginations of anyone who watches it, for the 600th time or the first time. There’s something magical and fresh about a flying DeLorean time machine.
