LOS ANGELES (AP) — The giant stuffed bear, its face a twisted smile, lumbers across the screen. Menacing music swells. Shadows mask unknown threats. Christopher Robin begs for his life. And is that a sledgehammer about to pulverize a minor character’s head?

Thus unfolds the trailer for the 2023 movie “Winnie the Pooh: Blood and Honey,” a slasher-film riff on A.A. Milne’s beloved characters, brought to you by ... the expiration of copyright and the arrival of the classic children’s novel into the American public domain.

We were already living in an era teeming with remixes and repurposing, fan fictions and mashups. Then began a parade of characters and stories, led by Winnie the Pooh and Mickey Mouse with many more to follow, marching into the public domain, where anyone can do anything with anything and shape it into a new generation of stories and ideas.
