Getting it right in the films (Was: Question for parents)

annoying and unnecessary.

Fake!Moody  has the same twitch.  And when Fake!Moody encounters
Crouch Sr. he gets agitated and twitches...and Crouch Sr. recognizes
him which is why Crouch Sr. is dead in the next scene.  

Carol:

Well, yes. But it was Barty Jr. who had the twitch in the first place,
before he became Fake!Moody (as we see in the Pensieve scene), and his
father recognized it in Fake!Moody before he was killed. But why a
tongue twitch? Something to do with Slytherin and snakes? We don't
even know that Barty Jr. was from Slytherin, and he's not a
Parselmouth. It just made him look mad (which he was) and served to
identify him, but didn't tie in with anything else in the movie or the
book. It was just thrown in out of nowhere like the shrunken heads in PoA.

va32h:
> But that whole thing is badly done - I've watched the film with
people who haven't read the books and they didn't even realize Crouch
Sr. *was* dead.

Carol:
Much less that Fake!Moody is his son and killed him, right? I agree
that it was badly done. And while I'm complaining, I didn't like the
casting of Barty Sr. He looked the part, with his weird little Hitler
mustache, but his voice and personality were all wrong. IMO only, of
course.

Carol, who liked parts of the GoF film (including the deleted Snape
scene with Karkaroff), but wishes they'd spent less time on the dragon
scene and more time making the Crouch!Moody plot clear, even if it
meant bringing in Jar Jar Binks, erm, Winky
