问题
I am trying to work with Freebase data dumps. I try to get only the films Ids by searching the predicates that starts with "film.film". But like that I got alot of unrelated items. this is a predicate for example:
film.film_character.portrayed_in_films_dubbed..film.dubbing_performance.film
which brings Id of this url:
http://www.freebase.com/m/0pc731y
which is not a movie but a character in a movie. Can anybody help me please???

If you do a prefix search, you're going to get anything which matches the prefix.
If you want IMDB ids, like your other question, you could search for:
ns:type.object.key\t"/authority/imdb/title
If you want all subject IDs of type film, you could search for:
rdf:type\tns:film\.film\.$
In other words, make your search expression match what you're trying to find.
