Hi, it's a US movie with an original English title. Based on that English is correct as original movie language (OML). Sometimes users confuse OML with the main spoken language, but that is not how it works. I did not see any OML changes, but plenty of spoken language changes (users from countries with dubbed versions sometimes add the dub language incorrectly). Thanks.

Thanks! I'll study the contribution bible some more. :)

Is there an API to grab the main spoken language btw? I think that's the data I'm actually looking for.

I don't think there is. All spoken languages are equal, as far as I know, so a movie can have English and Spanish listed even though there is only one conversation in Spanish in a particular movie.

Kk, thanks. If you're willing to indulge another question, I also came across these two movies:

Blue Iguana (2018) https://www.themoviedb.org/movie/471429-blue-iguana?language=en-US

The Sisters Brothers (2018) https://www.themoviedb.org/movie/440161-the-sisters-brothers?language=en-US

Neither have English as a spoken language, but afaict they should both have English listed. Would I be correct to go ahead and edit that in?

I'm using the API to run some analysis on my library and I stumbled across both of these as part of that. I'd like to contribute back, but want to make sure I'm not editing in bad data due to misunderstanding (like in my original question).

Would I be correct to go ahead and edit that in?

Yes, but since I had to check them now I fixed both anyhow. Thanks.
