Honestly, I think that it is not up to IMCDB to add these info as there is already a site supposed to do that, i.e. Varaces, but as this site does not seem to live a lot (not much update) and that IMCDB became so more complete, I guess it is a kind of info that we could include...
There is no need of such info, but it would not harm much. Retrospectively, I think that I should have added that rather than this "origin" country field that leads to so many discussions
