Disney's Steamboat Willie has officially entered the public domain, but there's a far better way to take advantage of this than with a horror movie. The copyright on this first iteration of Mickey Mouse expired as of January 1st, 2024, which means that anyone can now produce and distribute a film featuring the character. The overwhelming answer to this has been horror movies, and several Steamboat Willie slashers are now in the works. However, this alone indicates that the trend won't have lasting power.
