"Bonjour" to everybody... from France.
Concerning databases, there is a partial Japanese database, devoted to Horror, Fantasy and SF movies; it's in English too, and to date they have repertoried more than 1,000 titles, with complete cast/crew credits, notification of remakes, recurrent themes, etc. Here is the link:

For Korean films, there is a COMPLETE database and in English !!! I use this site since at least two years. You can make "selective" searches, for instance you can type "ghost films" and you'll have all the movies dealing with the subject, or having the word "ghost" in the title. Idem for actors, directors, technicians, etc. Plus, a synopsis virtually for each film, stills, and often reproductions of the posters !!! plus trivia like the release date, number of spectators, etc. The link is below:

For Indian movies, several databases exist, but I don't know if any is "complete". Some are for Marathi films, others for Hindi films, etc. But on Indian movies we have several books published, anyway.
For Thailand, it's really a problem, as for the Philippines, etc.
