Impressive. Your autocomplete suggestions are high quality, even in foreign languages. May I ask how you are ranking suggestions results? It can't simply be the TMDB api, right?
Re: foreign languages, they store very tidy information about all the available titles (basically a mapping from ISO 3166-1 to the title), cf. http://help.themoviedb.org/kb/api/movie-alternative-titles
Thanks for the feedback!
