Celebrate 30 years of Back To The Future with 13 insane fan theories

It is hard to imagine that we are now the same amount of time away from 1985 as Marty McFly was from 1955 in the original Back To The Future. A lot has changed in thirty years, but the love audiences have for Robert Zemeckis’ sci-fi romantic comedy hasn’t dwindled. Luckily, Back To The Future fanatics don’t have to worry about the adventures of Doc Brown and Marty McFly being rebooted anytime soon, but that doesn’t keep fans from creating scenarios in order to fill in plot holes in the Back To The Future series.
The internet really gave fan fiction somewhere to live and breathe: Fans have been creating their own adventures for their fictional characters for years, be it playing with action figures or penning lovelorn fantasies in their diaries. Nowadays, it’s easy to find folks who may read—or, in extreme cases, buy—your Doc and Marty slash fic. Back To The Future, like any fantasy series, has its own set of theories meant to explain away time travel and the many paradoxes of time travel. The Back To The Future series already features three different 1985s, possibly two 2015s (unfortunately we are not living in the one with Jaws 19), a 1955 where Marty tosses milkshakes at thugs, and one where Marty McFly looks like Eric Stoltz. There was even a Tannen dinosaur. What Culture has compiled a list of 10 of the most popular theories, and the blue-ribbon, fact-finding commission over here at The A.V. Club found a few more. Let’s go back in time, unless you’re chicken.
The first theory suggests that Marty McFly actually wrote two letters to Doc Brown warning Emmett that he would be killed by the Libyan nationalists on October 21, 1955. The theorist noticed that the letter Marty is writing in the café is quite different from the letter that Doc presents Marty in the first alternate 1985. While this is probably just due to the prop master not having the original letter when they were shooting pickups, this fan theory suggests that Marty had second thoughts about changing the future even though through his actions he possibly invented rock ’n’ roll as well as the skateboard, implying that he may have had a hand in developing punk as well.
This theory as is about as useful as a screen door on a battleship.
Another theory explored on the site explains that Doc Brown was suicidal. When the DeLorean first travels through time in the Twin Pines Mall parking lot, Doc stands in front of the time machine after explaining that his inventions never work. He pulls Marty by his side in hopes that the car will run them both down (and what of Einstein?). This theory is highly doubtful; sure, Doc never built his models to scale, but he was due for something he created to finally work. This ties into another theory that the DeLorean breaks down in order to prevent a paradox from occurring.
As the What Culture article states:
In Back To The Future, it [the DeLorean] breaks down in a place where it can easily be hid, so that nobody in 1955 sees such a futuristic vehicle and later fails to start just before the lightening strike—the delay means the car hits the wire at exactly the right time, almost as if it was compensating for an error in Doc Brown’s calculations. Clever DeLorean!
