In part, globalization is a limiting function on what makes sense to invest in. We do have data that says we make fewer comedies than we used to (they account for far less of the revenue percentage as well) and the reason is, in part, that comedies don’t translate well. The last 10 or so years has been dire for the genre.
There are other reasons too but it’s no wonder that studios are most interested in investing in movies that will have broad international appeal.
