One important note about the mouse shitting out live action remakes, they want to hold the copyright for as long as possible.
They don't care if Aladdin with Will Smith only makes a 10% return (Hollywood accounting), because they've renewed their claim on the IP and merchandising the blue corpse of Robin Williams Genie far exceeds any film profits. They make more than $5 billion per year just on licensing fees.
That's not how that works. 1. Aladdin isn't an original Disney story. Like Cinderella, it's an old story and anyone can make a version of it. 2. The timer on the animated film can't be reset. It's running and will continue to run. Steamboat Willie is the prime example of this. That version of Mickey is now in public domain, but later versions are not.
Winnie the Pooh isn't an original Disney IP either. Yet if you put Pooh in a recognizably Disney style Pooh costume they'll sue you. You can sell merch of shirtless Pooh all you like.
It's still protecting the Disney version of the IP. It's why the live action remakes still share a visual language with the animated originals.
You can make an Aladdin movie if you like. But god help you if there is a Blue Genie with characteristics recognizable to an objective observer as being similar to GenieĀ®.
Steamboat Willie is public domain, but Mickey MouseĀ® is not.
That doesn't mean Steamboat Willie is fair game either, Disney can still argue it's a trademark, and likely will, since they've made it the new intro clip to every Disney IP.
Here's an writeup covering it in more depth, from The Carey School of Business at Johns Hopkins:
Still no, because the timer started with the first release of the first product.
Yes, but now there are 2 versions of Genie with two different copywrite timelines. Both are still currently protected. (I will admit I haven't looked up if Genie is a registered trademark; still talking about copywrite here.)
Yes, but the Steamboat Willie Mickey Mouse character isn't the same as the registered trademark of Mickey Mouse.....but
