I am not sure to remember what has been said about that, but I also remember a discussion.
I would say the following then:
- as original title, it is better to keep the one that is used as main title on IMDB
- as English title, we can put the alternative title from IMDB, which is probably the one with "Ian Femming's" in some cases.
- it is nice to be able to do a search on "James Bond", but for that reason we could maybe add "- James Bond" at the end of the English title?
