Hollywood doesn't really do new movies
It does tons of them every year. You just don't go to see them.
I should have rephrased it to ones that make lots of money. That's what the Studios want is that next billion dollar franchise.
It's a good thing you said BILLION because "Us" $254 million worldwide against a budget of $20 million, Horror movies have always for the most done well with new IPs.
The Curse of La Llorona has grossed $54.7 million in the United States and Canada, and $67.3 million in other territories, for a worldwide total of $122 million, against a production budget of $9 million.
Pet Sematary has grossed $54.7 million in the United States and Canada, and $57.7 million in other territories, for a worldwide total of $112.4 million, against a production budget of $21 million
Escape Room has grossed $57 million in the United States and Canada, and $97.9 million in other territories, for a total worldwide gross of $154.9 million, against a production budget of $9 million
Those are all Indy type movies. There's not a lot being made between 50 to 100 million and the big movies production costs are exceeding the cost of making all those movies you listed.
first you state Hollywood doesn't really do new movies then you quantified: ones that make lots of money. Now you say name an original non MCU/DC movie that broke 500 million.
So, I'm starting to think you're moving the goal post.
There's only been a few big budget success movies in the last decade or so outside of the MCU/DC. Inception got 800 million and iirc that was the biggest one. In 2010.
Exclude Inception name an original non MCU/DC movie that broke 500 million.
Frozen.
If that's not "original" enough (it is inspired by a HCA tale afterall) then Zootopia.
BTW, a quick Wiki search also says that as of this July the $500M+ club only has 206 members.
