Original Movie Language (OML) =/= spoken language. This is primarily a US production that was first released in the US so the OML should be English. The Spoken Languages field is for whatever language is actually spoken in the film.

The wording of that label is a bit odd here. How does language of the country of production = movie language? Can we get the label for that field changed then? It would make much more sense if the field said 'Original Movie Production Language'. Without the missing adjective, my first thought of that filed is the meaning 'Original Movie Spoken Language'. A clarifying adjective would be really beneficial here as it could be interpreted either way without that detail, leading to this confusion.
