What to call information related to a film?
What is called a film's info such as year, director, country, actors, actresses, language, length... all the info related to it.
I don't want to say metadata or credits. Any other words?
EDIT: I want to find film equivalent of masthead (used in print)
That's not "metadata", it's just "data".
Edit: the approximate equivalent in film of a print publication's masthead is, I believe, the "billing block"; that's what appears at the bottom of a movie poster and on the back of the DVD label, with director info, main actors, run length, etc.
