Celebrating 40 Years of ‘Back to the Future’ With Hidden Gems

Tucked away in Robert Zemeckis' 1985 smash hit "Back to the Future" are countless clever references and secrets connecting to movies, TV shows, and real-world elements. As the film approaches its 40th birthday in 2025, a great blog, joblo.com discovered so many easter eggs that you probably missed in the ultimate time travel movie.

Pay attention to the opening scene - you'll notice a clock with someone hanging from its hands, a clever foreshadowing of the film's climax. This scene tips its hat to Harold Lloyd's famous stunt in his 1923 silent film "Safety Last!"

The movie got rejected 44 times before finally getting made. Even Disney turned it down, though Michael J. Fox wears Mickey Mouse shirts throughout several scenes.

Numbers play a big role in this movie. The clock tower sequence runs exactly 7 minutes and 22 seconds - matching the countdown to that crucial lightning strike.

Eagle-eyed viewers spot subtle changes between time periods. When Marty smashes through one pine tree in the past, Twin Pines Mall becomes Lone Pine Mall later. After timeline changes occur, part of the clock tower shows damage that wasn't there before.

Music helped create the magic. While Fox looked perfect on screen, Mark Campbell did the actual singing. Huey Lewis and The News contributed two hits, with "The Power of Love" landing an Oscar nomination.

The film borrowed elements from other Universal pictures. Those odd cat statues by the clock? Taken from the 1982 horror film "Cat People." The town square had previously appeared in "Gremlins."

Secret nods to crew members are scattered throughout. Spot "FOR MARY" on a license plate - that's for Mary T. Radford's contribution. The manure truck company name honors Dennis E. Jones, who managed production.

Writer Bob Gale chose November 5 for time travel because it's his father's birthday. He got the whole idea wondering if he would've been friends with his dad as a teenager.

Small details reveal the timeline changes. George McFly switches from Miller Lite to Miller High Life beer in the new future, showing his improved circumstances. The town's shops and signs change between eras to show time passing.

The plot connects to other famous stories. It shares themes with Mark Twain's time-travel tale "A Connecticut Yankee in King Arthur's Court." They even shot in the same location as "The Twilight Zone" episode "Where Is Everybody?" - both stories about being lost in time.
