Great Scott! Today is the day Michael J Fox's Marty McFly and Christopher Lloyd's Doc Brown travelled to in Back to the Future 2 in 1989.
BACK to the Future has become one of the world’s most watched and iconic films since its release in 1985.
The following sequels which completed the Back to the Future trilogy in 1989 and 1990 inspired a whole generation of aspiring time travellers.
For it was October 21, 2015, that Doc and Marty travelled to in the future in a bid to stop Marty’s son from going to jail.
We saw fingerprint technology, hoverboards, holograms and a drought-breaking World Series win for the Chicago Cubs.
Almost all of those predictions from the film are realities today (except for the Cubbies win but that dream may yet prove true in the coming weeks).
