   It doesn't apply to CC-by-sa. 

Indeed it does.  It is the whole point of a license, you cannot know
the license terms if you cannot see the license.

   Attaching the entire GFDL 1.2 text is not meaningfully "free" for
   photos or single-page texts. And how do you reasonably implement it
   for a motion picture.

This would fall under fair use.  But I fail to see what a motion
picture has to do with this, if you use a copyrighted work, you have
to note that, and its license.
