It’s common for actors with a few decades’ of acting credits to have a separate Wikipedia article for their filmography. In my opinion, this makes for an unnecessary hunt-and-click, seems a bit pretentious, and separates information that should all be on one page.
I’m not sure I understand what advantages there are of doing it this way. The article for a seasoned actor would have a really long chart in the middle of it, but what’s the harm? You can always click the link in the table of contents at the top to jump to the section you want . There are thousands of articles that are longer, vertically, than any actor’s page. Why make people hunt for the link to their filmography article?
