The trailer (Hagrid's line)

I know that Hagrid never says "Harry, you're the boy who lived"; 
however, I am not letting this bother me.  For one thing, I think it 
may mean that the bit in the book where people are meeting in secret 
and toasting "Harry Potter--the boy who lived!" is probably not in 
the film (just my opinion) and they wanted to get it in the film 
somewhere.  And for another, it wouldn't be the first time that a 
line is in the trailer but not in the final film version.  For 
example, when I went to see "My Best Friend's Wedding" I fully 
expected to hear Julia Roberts utter the line, "In situations like 
this, I try to figure out what Lucy Ricardo would do." (or something 
like that, my memory is a bit fuzzy) because it was in the trailer.  
But she never said it in the film.  So, we shall just have to wait 
and see!
