Potioncat:
Boy, was that annoying! It must have been the 3rd or 4th time of seeing 
the movie that I caught on, it was the movie's way of cluing us in that 
it wasn't Moody. That's how Crouch realised Moody was really his son.

I don't know why it took me so long to figure that out, except it's one 
of the movies I don't ever intentionally re-watch. If it happens to be 
on TV, I'll watch it for a little while. When all this was newer, I 
used to watch the first two fairly often.

I've cut the rest of Carol's post, but I'd like to second her questions 
to Steve or Carol Lynn or anyone else who is a movie fan and hasn't 
read the books (or hasn't memorized the books) how did you react to the 
sections Carol mentioned?

Or what is your reaction if you discover something from the movie was 
actually different in the books? Which version seems more valid?
