I don't personally see a point in doing this since we can click on the arrow beside 'Country' column title, then the arrow beside 'Type' to arrange movies separately by country for example. Similarly, click on Type and then Country to group the productions of each country and arrange them by type. Same goes for Year, Score , Priority columns and etc.
We can even arrange them by Score-> then Country -> then Type. this will separate Movies and Dramas completely, the you can see them arranged by country and then by score within country.
You can mix and match as you like.
But I agree with filtering by genre like some suggested.
