The Remis situation is all very interesting but back to JKR's comment
that she found that the film PoA inadvertantly foreshadowed Books 6 & 7---

I was wondering if anyone had any other thoughts on two other possible
foreshadowings (below), or any additional ones, not related to
whatever secrets Lupin might be keeping.

Stonehenge: Through Book 5, Stonehenge is not mentioned by name. It
is, to my knowledge, only foreshadowed in Book 5--if I'm reading the
tea leaves right. In OoP, there is some foreshadowing that we might be
headed to Stonehenge--the reference to Wiltshire on Page 307; the
release of OoP on June 21, the many references to circles and stones.
 PoA was largely filmed  by the time of the release of Book 5, and
certainly the sets were finished.  In the film of PoA we see
Stonehenge-like monoliths. I wonder if that is what JKR is referring
to.  Wouldn't we be disappointed if an English Mystery about Wizards
didn't take us to the most famous mysterious site in England?

Dementors:  Targeting Harry specifically as early as PoA? Certainly in
the books, it's an open question whether or not the Dementors want to
get Harry too. In the film, they seem to really want to get him. It's
not till Book 5 that we see the Dementors again, sent on purpose. Is
it possible that the Dementors were playing a double role earlier? On
their own or under instruction?

Any other ideas on foreshadowing that might have inadvertently been
revealed in film that JKR is referring to?
