History YMMV / BackToTheFuturePartII

** The ''USA Today'' front page in 2015 mentions the U.S. preparing for ''Queen'' UsefulNotes/{{Diana|Princess of Wales}}'s visit. Unfortunately, in the real 2015, Diana had been dead for 18 years (and she divorced from [[UsefulNotes/CharlesIII Prince Charles]] the year prior, so even if she were still alive, she wouldn't have been queen). Then again, that also would suggest that UsefulNotes/ElizabethII had died prior to that, when in real life, she was still on the throne and reigned until her death in 2022. On the real October 22, 2015, ''USA Today'' released its print edition with the front page from the film. All the original headlines were retained, except for the one about Queen Diana, which was replaced with a headline about 3D billboards.

** The Chicago Cubs are depicted as winning the World Series on October 21, 2015. On the real October 21, 2015, the Cubs lost the National League Championship, preventing them from going on to the World Series. They did win the World Series the following year, though.

** The movie depicts the then-common predictions that Japan would overtake the United States economically, with Future Marty working for a Japanese company. By 2015, Japan would be amid economic and demographic stagnation.

* UnintentionalPeriodPiece:
** While the creators weren't trying to create a ''serious'' prediction of life thirty years down the road, depicting 2015 with flying cars, hoverboards, and waste-to-energy powering home electronics isn't at all what life in 2015 would be.
** Marty working for a Japanese boss was keeping the 1980s view that Japan was returning to superpower status and would overtake the United States. But just after 1989, Japan would enter its Lost Decade and has remained in an economic and social spiral.

* ContestedSequel: In contrast to the near-universal love the original film has enjoyed, ''Part II'' has many detractors due to its complicated storyline and for being more focused on the sci-fi aspect than the heart and character relationships of the first film. However, ''Part II'' also has many fans of its own, who enjoy it precisely for its brisk pace and intricate plot, and its darker, more epic and adventurous feel.

** Witnessing Future Marty getting fired from his job due to being goaded by Needles into participating in an illegal deal by exploiting his FatalFlaw and calling him chicken. It would've been a heartbreaking and harrowing moment if it weren't for the fact that his boss is [[LargeHam an over-the-top ham]] who immediately confronts him about it and proceeds to send a fax with big, bold letters reading "'''YOU'RE FIRED!!!'''" to ''every fax machine'' in the [=McFly=] household, all while Future Marty [[NeverMyFault tries to blame Needles and]] [[BlatantLies claim it was a sting operation]] and is left pathetically bemoaning his situation.

** The kids in the Cafe '80s insulting the Wild Gunman arcade game because you had use the controls by hand. The [=XBox=] Kinect attempted to be the first controller-less device in 2010... and while initially successful, it was soured by lackluster games which didn't take advantage of the Kinect's strengths and limitations. When a more advanced (and thus expensive) iteration of the device was bundled with their next console, the UsefulNotes/XboxOne, there was immediate backlash that contributed to the console's sales. When the bundle was dropped, all interest in the Kinect dried up and it would be discontinued in 2017, two years after the future 2015 of this movie. Even VR devices at the time of this writing still use controllers by hand. Guess the "baby's toy" still wins.

** When Doc and Marty arrive over Hill Valley, California on October 21, 2015, they're in the middle of a rainstorm. On the real October 21, 2015, California was in the middle of its worst drought in recorded history.

** The scene of Marty finding his father's grave is even sadder given that Michael J. Fox's father died only two months after the film's release.

** Relatedly regarding how low Old Biff is willing to go, we don't actually hear what Old Biff told his younger self to do regarding Marty and Doc. Did he specifically tell his younger self to [[spoiler:kill them, or did he simply say to deal with them somehow, and the more monstrous 1985-A Biff, when the opportunity arose, took it upon himself to kill them?]]

** Speaking of the kids in the 80s cafe, one of them is played by Creator/ElijahWood in his first film role. Interestingly enough, this won't be the last time Wood is [[WesternAnimation/OverTheGardenWall involved in a production that features Christopher Lloyd.]]

** In the DVDCommentary, Bob Gale praised the special effects that allowed Creator/ThomasFWilson to act as Young and Old Biff at the same time, but took issue with the poorly animated almanac tossed into the backseat by Young Biff.

** In the same scene, stunt dolly wheels can be seen under the [=DeLorean=] -- which is in hover mode at the time -- in a brief shot of Marty's feet as Marty is about to grab onto Biff's car.

** Pay attention to the [=DeLorean=] when it makes its alleyway landing in the future at the beginning. It switches several times to a model with MUCH less detail than the actual "hero" car. The [[http://backtothefuture.wikia.com/wiki/Rear_louver rear louvers]] in particular are horribly OffModel; they don't extend over the taillights like they're normally supposed to.

** The "flying" version of the car used with the actors -- particularly in the scenes where Doc rescues Marty from the top of Biff's tower and where Marty uses the hoverboard to jump from the [=DeLorean=] onto Biff's car -- has a front DMC grille emblem that is much larger than normal and looks like it's made out of painted cardboard.

Later on, when Marty, Dock, Jennifer, and Einstein arrive in 1985A and land on the street in front of her house to drop her off, the flying version of the car is clearly a model shot on a blue screen composited into the shot of the night sky before it passes the lamppost that shows up in front of the camera and switches to the real car. It's obvious because of the bad lighting contrast on the model that makes it stick out against the night sky.
