Where to find usable photos?

[Glove]

I'm just getting into this so I apologize if this is just common knowledge but where can do people get photos or videos to use? Looking through the swap share thread, it seems like most of those must have taken thousands of photos to train. I was thinking about trying to find and download an interview with the subject but then it wouldn't be a very diverse set of images. Hopefully what I'm looking for makes sense, thanks for any help.

Interviews, films, tv shows etc. Videos tend to be more useful as they are less posed and more naturalistic.

"Staged" content (i.e. films/tv) tend to be better because they tend to have a better variation of more natural lighting, and a wider range of expressions and poses. The more sources you can find, the better.
