This time, it's really, really personal.
It's been a busy couple of months for fans of Back to the Future. Not only is it the 30th anniversary of the original's release, but Oct. 21 will mark the exact date when Doc Brown and Marty McFly arrived in Back to the Future 2's future.
Many people are celebrating in different ways. Some are building awesome DeLorean golf carts. Some are helping you build your own hoverboard. And Christopher Lloyd put his lab coat back on.
Universal Studios decided to celebrate by putting together a trailer for Jaws 19, the movie featured at Hill Valley's cinema.
And it's a lot of fun to watch.
