Winnie the Pooh stars in an R-rated slasher movie

The Hundred Acre Wood has seen some pretty unsettling things over the years. A honey jar shortage. Rather blustery days. The omnipresent threat of a Heffalump.

But in “Winnie the Pooh: Blood and Honey,” a new microbudget R-rated horror film, Pooh wades into far darker territory than even Eeyore could have ever imagined. After 95 years of saying things like “A hug is always the right size,” Pooh — newly freed from copyright — is now violently terrorizing a remote house of young women.

Countless cherished characters have passed into public domain before, but perhaps never so abruptly and savagely as Pooh.

Pooh, Piglet, Kanga, Roo, Owl, Eeyore and Christopher Robin all became public domain on January 1 last year when the copyright on A.A. Milne’s 1926 book, “Winnie-the-Pooh,” with illustrations by E.H. Shepard, expired. Just a year later, Pooh and Piglet can now be found on a murderous rampage in nationwide movie theaters — a head-spinning development that’s happened faster than a bear could say “Oh, bother.”

Depending on how you look at it, “Winnie the Pooh: Blood and Honey” is either a crass way to capitalize on a beloved bear or an ingenious bit of independent filmmaking foresight. Either way, it’s probably a harbinger of what’s to come.

In the next 10 years, some of the most iconic characters in pop culture — including Bugs Bunny, Batman and Superman — will pass into public domain, or at least their most early incarnations. Some elements of Pooh are still off-limits, like his red shirt, since they apply to later interpretations. Tigger, who debuted in 1928’s “The House at Pooh Corner,” isn’t public until 2024.

Many have next Jan. 1 circled. That’s when the original version of Mickey Mouse, from “Steamboat Willie,” becomes public domain. It will be open on season on the face of the Walt Disney Co. — or at least that early whistling variety of Mickey.

Pop culture, as a concept, was born in the 1920s, meaning many of the most indelible — and still very culturally present — works will fall into public domain in the coming years. There will be all kinds of new and unlikely contexts for some of these characters. Some could be wonderful, some schlocky. But “Winnie Pooh: Blood and Honey” may just be a taste of what’s in store.

“When Superman and Batman fall into the public domain, there’s going to be some wild films, I’m sure of it,” says “Winnie the Pooh: Blood and Honey” writer, director and co-producer Rhys Waterfield. “There’s going to be so many different and cool unique iterations coming off that. I might do one.”

Though made for less than $100,000, “Winnie the Pooh: Blood and Honey” will open Friday on some 1,500 screens in North America, an unusually wide release for such a little-funded movie. It’s already made $1 million in Mexico and has many more international territories booked. For Waterfield, a British film producer of direct-to-DVD titles (credits include “Dinosaur Hotel” and “Easter Killing”), it’s already a hit way beyond expectation.

In a 2021 tally of media franchises by Statista, Winnie the Pooh, with $80.3 billion in worldwide revenue, tied Mickey Mouse for No. 3, trailing only Pokémon and Hello Kitty. But unlike them, Pooh accounts for a veritable religion for his kind-hearted witticisms and contented spiritual outlook. Pooh is as much a gentle sage as he is a round-tummied toon. When Waterfield realized Pooh was entering public domain, “I had a spark in my eye,” he says.

Here was much-coveted intellectual property that could sell just about any film. “I’ve never met anyone that doesn’t know who Winnie the Pooh is,” Waterfield said in a recent phone interview speaking from Amsterdam.

But certainly, not everyone has been so happy about the idea of one of the most benevolent bears turning feral monster. Waterfield says he receives daily messages telling him he’s evil, and even some death threats. One person said they were calling the police.

Waterfield is already planning sequels with Peter Pan, Bambi and many more. (The Felix Salten book “Bambi, A Life in the Woods” also became public domain last year.)

Jennifer Jenkins, a professor of law and director of Duke’s Center for the Study of Public Domain, is used to operating in a relatively quiet and byzantine realm of copyright law and thorny rights issues. She writes an annual Jan. 1 column for “Public Domain Day.” But nothing has caused her phone to ring off the hook quite like “Winnie the Pooh: Blood and Honey.”

The movie has clearly touched a nerve; millions have watched its trailer online. (Typical comment: “I can’t believe that this movie is real.”) And Jenkins, a firm believer in the long-range benefits of public domain, has been somewhat bemused by the storm kicked up by a movie like “Winnie the Pooh: Blood and Honey.” She compares public domain issues like these to the way free speech is a right, regardless of whether you agree with what’s said.

It’s worth noting that much of the Disney empire was, itself, built on public domain. “Beauty and the Beast” comes from Jeanne-Marie Leprince de Beaumont’s 1756 version of the fairy tale. “Sleeping Beauty” came from Charles Perrault’s 1697 fairy tale. “Aladdin” comes from the folk tale collection “The Book of One Thousand and One Nights.”

Though Jenkins can’t think of too many characters who had such a jarring entry to public domain as Pooh, films like “Pride and Prejudice and Zombies” (2016) and the 2021 book “The Great Gatsby Undead” are reference points.

To her, “Winnie the Pooh: Blood and Honey” may not be the most glorious example of the effects of public domain, but it’s part of a process that human creativity depends upon and thrives on. “Blood and Honey” may not make a lasting mark in the Hundred Acre Woods, but something, someday will. Chalk it up to growing pains.

“The fact that some people may be disturbed or revolted by this particular re-use of some of the characters from Winnie the Pooh doesn’t detract from the value of the public domain,” says Jenkins. “This is how people throughout history have created. They’ve always drawn on or been inspired by earlier works. Time will tell with this movie or any other reuse of Winnie the Pooh and Piglet whether movies like this will be rewarded in the marketplace or have any enduring appeal.

“My thing is always: Time will tell.”
