I think I know why Tarzan returned in Once Upon A Studio (I could be wrong though)
I know the Burroughs estate is a litigious bitch, but before Tarzan returned in Once upon a Studio and the remake rumors. Disney had to “acquire“ the film rights to the film rights to Tarzan and they didn’t use him for years cause fans claimed Disney had no rights, but here is the thing. Tarzan is in the public domain!
The first book, Tarzan of the Apes by Edgar Rice Burroughs was published in 1912, under the old law and because it was renewed on time it entered the public domain in 1987. Some later Tarzan works made after 1930 like the newspaper comic until 1935 and some books and movies are also public domain as they weren’t renewed. As of 2026, most of not all of the Tarzan books by ERB entered the public domain in the United States.
Yet because of the weird using trademarks as mutant copyright law thing, despite Dastar vs Fox ruling this as invalid the estate is nroable for being litigious and has sued people like Dynamite, despite this they weren’t that successful as there were still unauthorized Tarzan works like the golden films adaptation. because they had a “trademark“ on Tarzan, its why Disney had to “acquire” the rights and also likely due to the later books being copyrighted or whatever.
However despite Tarzan not appearing in Kingdom Hearts due to claims of rights and such, it’s not that accurate.
Because of the characters public domain status and because it is likely Disney still owns the rights to their version of the character and because since 2019 all of Burroughs works fell out of copyright in Europe, Disney seems to being Tarzan again in some media such as The Simpsons and Once upon a Studio.
I honestly hope this is the case because having to “acquire” rights to a public domain work is complete crap in my opinion, this happened with Zorro and Conan (yes Conan is public domain as the characters debut was never renewed, yet Conan Enterprises claims they own the character.) Estates using trademark law to bypass copyright is always a failure..
Feel free to disagree, but while I am a Stitch fan we deserve more Tarzan content.
