As anyone who's seen Back to the Future II will tell you, the flick made some bold predictions for what would be happening in the world on Oct. 21, 2015.
According to the 1989 sequel to the monster-sized hit original, we'd all be riding hoverboards around, we'd have flying cars, and the Chicago Cubs would finally win the World Series. We have no hoverboards and our cars are sadly still grounded, but hey, the Cubs are in the baseball playoffs, so that's something.
In Back to the Future II, lead character Marty McFly also sees a movie preview for Jaws 19, a funny gag about how common big-budget movie sequels were becoming at the time Back to the Future II (a big-budget movie sequel, of course) arrived in theaters. To help celebrate the 30th anniversary of the original Back to the Future, Universal Pictures put out a gag trailer for Jaws 19, and I would rather see it than another Sharknado sequel.
