Let your conversation possess a clarified conciseness, compacted comprehensibleness, coalescent consistency, and a concatenated cogency. Eschew all conglomerations of flatulent garrulity, jejune babblement, and asinine affectations. Let your extemporaneous descantings and unpremeditated expatiations have intelligibility, without rhodomontade or thrasonical bombast. Sedulously avoid all polysyllabical profundity, pompous prolixity, and ventriloquial vapidity.

“… for the rest of us, learn to read subtitles”

— Mark Kermode, on accents in films. I agree with him that films really ought to be made in the language most relevant to the film, rather than the one most relevant to the audience.
