Yeah the superhero and big action movies play well around the world.
China is notoriously protectionist of its movie industry, even before the new Trump tariffs they only allowed 34 import films per year. So I'm not particularly sad if a movie tariff is applied against them, although I can't imagine we import very many Chinese films annually anyway.
As far as the rest of the world goes, are they really stealing production from the USA? I know Canada has a strong movie industry, but in general I think films shot in Europe and Asia, are done so because that's where they are set.
I do know that Disney has shot most of the Star Wars films in England ever since they acquired Lucasfilm, and I believe they shot a bunch of the Marvel stuff over there too.
So maybe it's a shot against Canada and Disney?
