I would expect the Spanish market to be a lot more international since there isn’t one country that could dominate the way the US dominates the English market.
Mexico has 2.5 times more people than Spain, but the two countries have a similar GDP. There are also other close countries like Colombia and Argentina. In contrast, the USA has over five times the population of the UK with the USA having a higher GDP per capita than the UK. Other English speaking countries either have local languages to compete with, have far smaller populations, and/or have lower GDP per capita.
Hollywood needs the foreign market, now more than ever. However, it is really hard to compete with the giant that Hollywood is in its local market in English, let alone a foreign language.
