When writers Robert Zemeckis and Bob Gale sent protagonist Marty McFly thirty years into the future in Back to the Future Part II, they made a number of incredible and imaginative predictions of what the year 2015 might look like. While a number of the screenwriting duo’s loftier ideas for what the future might contain have not yet come to fruition, the film managed to foresee a surprising number of the technological advances which society has made in recent years.

Upon its 1989 release, Back to the Future Part II was a commercial success and grossed $331 million worldwide. While the film received generally favorable reviews, some critics mocked the writers’ ideas of the future, commenting that the flat-screen TV’s and holographic displays which they hypothesized may be commonplace in 2015 couldn’t possibly become real so soon. Zemeckis and Gale proved to be near prophets in recent years, as more innovative versions of flat-screen TV’s come out each year, and the world’s first see-through television is scheduled to come out in 2015. While modern billboards don’t feature holographic sharks advertising the release of Jaws 10, Tupac’s resurrection in 2012’s Coachella festival proved that the technology is definitely available should film studios choose to utilize it.

Back to the Future Part II also featured dog-walking drones, and while drones of that caliber aren’t necessarily available to the public, they have been making headlines for years and are expected to become more prominent in the consumer market this year. Biometric identification seemed to be one of the most unlikely technological advances in the film, but in 2015, several companies allow users to unlock phones and computers with their fingerprints and the Nymi band will allow consumers to open doors by using their unique heartbeats.

However, much to the dismay of the film’s biggest fans, not all of the predictions of Back to the Future Part II proved to be correct. While plastic surgery and Botox can have a similar effect as the film’s rejuvenation mask, people cannot simply go to a clinic, peel a mask off of their face, and immediately look young and beautiful. The hoverboard Marty McFly uses in the film as a replacement for his staple skateboard from the first Back to the Future film still doesn’t exist, and people still can’t purchase a flying car either. Most consumers are probably happy that fax machines aren’t nearly as prominent as the film’s depiction of 2015 predicted and that there aren’t typically stationary bicycles in modern cafes, but countless children would benefit from the self-lacing shoes featured in the film.
