Today, October 21, Is National Back To The Future Day - Here Are Some Fun Facts

The time machine was almost a refrigerator — Before choosing the DeLorean, the writers originally planned for Marty to time-travel in a fridge!

Eric Stoltz was the original Marty McFly — He was replaced by Michael J. Fox after several weeks of filming because the tone wasn’t quite right.

The clock tower scene took weeks to shoot — The iconic lightning strike finale was filmed over several nights on a massive backlot set at Universal Studios.

The DeLorean’s speed of 88 mph wasn’t random — the filmmakers picked it because it sounded cool and looked good on the car’s digital display.

Crispin Glover didn’t return for the sequels as George McFly, leading to a lawsuit over the use of prosthetics to recreate his likeness.

Michael J. Fox filmed “Family Ties” and “Back to the Future” at the same time, often sleeping only a few hours a night while switching between sets.

“Johnny B. Goode” wasn’t played by Chuck Berry in the movie — it was actually performed by musician Mark Campbell with Harry Waters Jr. lip-syncing.

The Hill Valley town square was a reused Universal Studios backlot set that’s appeared in countless films and shows, including Gremlins and The Twilight Zone.

The sequels were filmed back-to-back, an uncommon move at the time that saved money and kept continuity between Part II and Part III.

Hoverboards aren’t real (yet) — but after Part II premiered, so many people believed they were that director Robert Zemeckis had to publicly deny their existence!
