You’ve probably seen it by now. Maybe it popped up on your YouTube feed with a thumbnail featuring Tom Holland looking startled in a red puffer vest, or perhaps a friend sent you a "leaked" clip on TikTok. The back to the future 4 movie trailer has become a sort of digital urban legend in 2026. It looks real. It sounds real. It has that iconic Huey Lewis beat and the crackle of blue electricity hitting a DeLorean.
But honestly? It’s not real.
We need to talk about why these trailers keep surfacing and what’s actually happening behind the scenes in Hill Valley. Because while the footage is getting incredibly good, the reality of a fourth film is a lot more complicated than a two-minute teaser.
The Truth Behind the Viral Trailers
Let’s be real—the people making these "concept" trailers are talented. They’re using high-end AI and deepfake technology to graft Tom Holland’s face onto 80s-era footage or splicing together clips from Spider-Man and The Adam Project. Some of the most popular videos currently floating around YouTube, like the one from the channel Smasher, have racked up millions of views by promising a 2026 release date.
They often pitch a story where Marty McFly Jr. (Holland) has to save his father (Michael J. Fox) from a "temporal fracture." It’s a great hook. It pulls at your nostalgia strings. But if you look closely, you’ll see the "Concept Trailer" or "Fan Made" disclaimer buried in the description.
Why do they keep going viral? Basically, we’re all desperate for that lightning to strike twice. We want to see Christopher Lloyd’s Doc Brown jump out of a flying train one more time. The 2026 date often attached to these videos is just a placeholder—a bit of "wishful thinking" SEO that keeps people clicking. There is currently no official production, no script, and definitely no secret filming happening with Tom Holland.
Why Robert Zemeckis Won't Budge
If you want to know why we don't have a real back to the future 4 movie trailer, you have to look at the contracts. Director Robert Zemeckis and writer Bob Gale have a literal "ironclad" grip on the franchise. Back in the 80s, they signed a deal with Universal and Amblin that gives them final say on any sequels or remakes as long as they are alive.
And they’ve been very, very clear about their stance.

Zemeckis has gone on record multiple times—including a recent 2024 interview on the Happy Sad Confused podcast—saying that a fourth movie "just isn't in the cards." He’s compared the idea of a reboot to selling his own children. He once famously joked that Universal checks in with him "every six months" to see if he's changed his mind, and every time, the answer is a firm no.
Bob Gale is even more protective. He’s argued that the trilogy is a "three-act drama" and that adding a fourth part would be like adding a fifth leg to a chair. It’s "perfect enough" as it is. They don’t want to be the guys who ruined a perfect legacy for a quick cash grab. Honestly, you kinda have to respect that in an era where every single 80s property is being rebooted into oblivion.
What the Original Cast Actually Says
It’s not just the directors. The actors themselves have a complicated relationship with the idea of returning. Michael J. Fox, who we all love as Marty McFly, has been pretty candid about his health. While he still makes public appearances and is incredibly active in Parkinson's research, he’s basically retired from the kind of high-octane acting a Back to the Future sequel would require.

Fox told Variety that he doesn’t think the movie needs a reboot. He said, "I don't think it needs to be... are you going to find a better way to tell the story? I doubt it." He’s even joked that he "already got paid," so he doesn’t feel the need to go back.
Christopher Lloyd, on the other hand, is the eternal optimist. Even at 87, he’s still saying he’d love to do a sequel if someone had a "brilliant idea." He’s still got that Doc Brown energy. But without Fox and without the original creators, it’s hard to imagine Lloyd carrying a film on his own without it feeling like a hollow spinoff.
The Tom Holland Rumors
Where did the Tom Holland thing come from? It started with a deepfake video back in 2020 that went insanely viral. People realized that Holland has that same frantic, "everyman" energy that Michael J. Fox had in 1985. Holland himself has acknowledged the rumors, even admitting he’s had conversations about it in the past, but he’s also said that the original is "one of the most perfect movies" and shouldn't be touched.
The Closest We’ll Get to a Sequel
If you’re craving more time-travel content and that back to the future 4 movie trailer left you feeling empty, there are actually "official" ways the story has continued that most people ignore.
- The Telltale Video Game (2010): Bob Gale actually helped write this. It picks up six months after Part III and features the voices of Christopher Lloyd and even a cameo from Michael J. Fox. Gale considers this the "closest thing to a fourth movie" we’ll ever get.
- The Musical: It’s been a massive hit in London and on Broadway. While it's a retelling of the first film, Zemeckis has actually said he’d be more open to a movie version of the musical than a direct sequel.
- The IDW Comics: These stories fill in the gaps, like how Doc and Marty first met or what happened to Doc while he was living in the Old West.
Actionable Next Steps for Fans
Stop waiting for a "leak" from a major studio. It’s not coming. If you see a back to the future 4 movie trailer on social media, check the source. If it’s not from Universal Pictures or Amblin, it’s a fan creation.
Instead of chasing rumors, here is how you can actually engage with the franchise:

- Watch the 40th Anniversary Re-releases: With 2025 and 2026 marking major milestones for the franchise, keep an eye out for 4K restorations in theaters. There's nothing like seeing the DeLorean hit 88 mph on a 50-foot screen.
- Check out the "Search for Marty" Web Series: Some creators are making high-quality, non-profit fan films that actually try to tell a new story rather than just making fake trailers.
- Support the Michael J. Fox Foundation: If you want to honor the legacy of the man who made Marty McFly iconic, supporting Parkinson's research is the best way to do it.
The future hasn't been written yet, but for this specific movie franchise, the past is pretty much set in stone. And maybe that's a good thing. We don't need a mediocre sequel to tell us that where we're going, we don't need roads.
