country as i understood is the country where the movie was made and released
No, it's the countries that PRODUCED the movie. Many movies are international productions.
but according to iMDB includes also the country where the movie was filmed
The countries where the movie is filmed are frequently associated to the production (as they provide filming authorizations, logistics, etc...).
you mentioning the video and movie language as separate things, please clarify this one, what's the difference between them?
I don't know in what language a movie was shot. I don't have access to that information (it's very frequent for movies to be shot in English, even if it's a french movie for example). The only information I do have is the language of the DVDs.
for me, both are same and they are the language spoken in the movie.
And for me it's quite different. On one side, there's an information that I have. And on the other side, there's an information that I don't have. I'm not a magician. I just apply filters to a database.
B.D. în alerta (1970) .jpg is a totally romanian movie
Our database doesn't have any existing video for that movie. No video => no language information.
ohhh, and something more, i do not crossfiltering now, i only filter by language/country now trough all movies ( not just owned....) so i cannot mess up things.
Sorry, but you're messing up things
