‘MARCELLUS THE OCTOPUS WAS NEVER SUPPOSED TO STEAL THE MOVIE’: HOW A GIANT CGI SEA CREATURE QUIETLY BECAME NETFLIX’S MOST EMOTIONAL CHARACTER, LEFT MILLIONS OF VIEWERS CRYING ONLINE, AND TURNED ‘REMARKABLY BRIGHT CREATURES’ INTO A GLOBAL OBSESSION NOBODY SAW COMING

When Netflix released Remarkably Bright Creatures, most viewers expected a quiet emotional drama led by legendary actress Sally Field.

Nobody expected the internet to fall completely in love with an octopus.

Yet within days of the film’s release, Marcellus — the sarcastic, deeply intelligent giant Pacific octopus at the center of the story — became one of the streaming platform’s most talked-about characters, sparking emotional breakdowns, fan theories, and viral reactions across TikTok, Reddit, and film forums worldwide.

What shocked audiences most was not simply how realistic Marcellus looked.

It was how human he felt.

Viewers described the creature as “heartbreaking,” “wiser than every human character,” and “the emotional soul of the film,” with many admitting they unexpectedly cried harder over the octopus than over most recent Hollywood dramas.

Based on the bestselling 2022 novel by Shelby Van Pelt, the Netflix adaptation follows Tova Sullivan, played by Sally Field, a lonely widow still haunted by the decades-old disappearance of her son. While working night shifts cleaning a small-town aquarium, she forms an unusual connection with Marcellus, a giant Pacific octopus who quietly observes the humans around him with almost unsettling emotional intelligence.

But behind the emotional phenomenon lies an even stranger truth:

Marcellus was never real.

According to Netflix and the film’s visual effects team, the octopus audiences became emotionally attached to was almost entirely CGI, painstakingly animated over months of work to feel emotionally alive. The production reportedly spent enormous effort studying real octopuses, including one named Agnetha at the Vancouver Aquarium, to recreate realistic movement, behavior, and personality traits for the character.

Visual effects supervisor Chris Ritvo described octopuses as “basically aliens,” explaining that every tentacle, sucker, texture shift, and skin movement had to be individually animated to make Marcellus believable on screen. Some scenes reportedly took up to 12 weeks to complete.

And somehow, all that technical work created something viewers now describe as emotionally devastating.

Part of the obsession comes from the mystery hidden inside the story itself.

As the film unfolds, Marcellus slowly begins piecing together clues surrounding Tova’s missing son, Erik, eventually uncovering a heartbreaking connection between Tova and Cameron, a drifting young man who unexpectedly arrives in town searching for answers about his own past.

Fans online have become fixated on the idea that Marcellus understands the truth long before the human characters do.

Several viewers admitted they immediately rewatched the film after realizing the octopus appears to subtly guide the story toward its emotional conclusion from the very beginning. One scene in particular — involving a missing ring and Marcellus’ final escape from the aquarium — has become the emotional centerpiece of countless TikTok reactions and online discussions.

The emotional attachment to the character has only intensified because of Alfred Molina’s performance.

The actor, famous for playing Doctor Octopus in Spider-Man, voices Marcellus with dry humor, intelligence, and quiet sadness that many viewers say made the creature feel “more emotionally honest than the humans.”

Critics remain divided over the film itself.

Some reviewers praised Remarkably Bright Creatures as one of Netflix’s most heartfelt releases in years, while others argued the movie leans heavily into sentimentality and emotional manipulation. Yet even skeptical critics admitted the bond between Tova and Marcellus was difficult to resist.

Still, the most fascinating part of the phenomenon may be what audiences continue saying after the credits finish.

Across social media, thousands of viewers are now repeating the same emotional realization:

The octopus was never just comic relief.

He may have been the only character who understood the truth from the very beginning.
