Work out the difference in revenues made between the English and Latin movies.
English refers to language_name = 'English'; Latin refers to language_name = 'Latin'; difference in revenues = subtract(sum(movie_id) when language_name = 'English', sum(movie_id) when language_name = 'Latin')
SELECT SUM(CASE WHEN T3.language_name = 'English' THEN T1.revenue ELSE 0 END) - SUM(CASE WHEN T3.language_name = 'Latin' THEN T1.revenue ELSE 0 END) AS DIFFERENCE FROM movie AS T1 INNER JOIN movie_languages AS T2 ON T1.movie_id = T2.movie_id INNER JOIN language AS T3 ON T2.language_id = T3.language_id
