Hi,
 
this is a reply to Lutger Kunst's mail.
 
i have foreign movies to. what  i did is that i created an extra field, an orgtitle field named original title. 
this can be done by clicking to configuration from the menu. then scroll down until you see custom fields. you can create 4 custom fields. on the left side you choose the name (like Original Title) and on the right you choose orgtitle.
 
now, when you add a new movie, you have the option to fill an extra field called orgtitle. in that field you can add the english translation and in the title field you can add the real japanese name.
 
you now can search. when you search for title, search with the japananese names, when you search for the english search with origirnal title.
