Sorry, I know it is a little selfish, but it is the only one displayed on french.imdb.com that I use, and I usually do not take time to put the full list
The alternative titles list was not made for adding ALL titles, but rather to add various alternative well known titles. As I said elsewhere lots of movies are well known by their French title here, I do not know if it is the case in many other languages (well, it would be logical, but who knows).
