I love the new app Callsheet because it's like a better, faster, streamlined IMDB, and over a couple weeks of using it, it has consistently given me better info on "who was that guy in that thing?" questions (even down to specific cast lists for each individual episode!) while you watch shows and movies. Hearty recommend and worth the small annual fee: https://www.caseyliss.com/2023/8/7/callsheet

@mathowie Or, just use the free website this paid app is scraping its data from: https://www.themoviedb.org/
The Movie Database (TMDB)

The Movie Database (TMDB) is a popular, user editable database for movies and TV shows.

@messick @mathowie I’m not sure you understand why musicbrainz.org, themoviedb.org, thetvdb.com, or the myriad other metadata sites exist, because it’s to make the data maintained by contributors available to everyone - including app developers who offer a better experience through their app. No one is “scraping”, “stealing”, or in any way misusing the data that was contributed exactly for this purpose.
