Two database and menu on different page

Friends,

in fdbn are sections in which the list of contributions – be – what we expect / May and it is a list of movies when I select a movie and forwarded to film.fdbn.cz, where there his website and his menu (reviews, videos and gallery). U film.fdbn.cz nothing other than just movies.

I need advice on how to do this?

http://film.moviezone.cz/pravidla-mlceni/recenze/
