Ootp movie changes--effect on DH--ALLOWED?

If we want to discuss the differences (additions/deletions)
between the Ootp movie and novel, and what the changes might
possibly tell us about the upcoming DH novel, would that be
allowed here? I know the movies aren't to be discussed here
in general, but if the discussion pertains directly to what
may happen in DH, that seems a gray area to me, and I didn't
want to post anything without knowing for sure. If it is 
allowed, presumably SPOILER would be required in the subject
header in regards to the movie.

Thanks, 
Julie
