Interesting pre-FX notes and deleted scenes?

All right, well being the dork that I am, I decided to go back and 
watch the trailers again to see if there was anything that changed 
between them and the movie, and there are at least 3 things I can 
pick out obviously as interesting

1) In the first trailer there is quite a bit of pre-FX shots in the 
Chamber, like the part where the basilisk hits the statue instead of 
Harry, and Harry killing the basilisk, only all of the shots from the 
trailer are basilisk free, so it's quite amusing to see it now after 
the movie has come out.

2) There must have been a scene shot where the boys nearly drive the 
Anglia into a clock tower, because you can see them avoiding it in 
one trailer, and the reflection of the clock's face in another.  
Perhaps the filmmakers thought one near-miss was just enough.  But in 
the movie, you can see what I'm assuming is the tower they're 
supposed to run into just as they lift off in the car.

3) Harry and Ron dragging Crabbe and Goyle into the closet.  Not that 
big a deal, but maybe there was something else with that bit, like 
pulling out the hairs, as I don't imagine they'd film a tiny bit like 
that for nothing.

That's all with the trailer stuff.  I found it interesting, so I 
thought a few of you all might also.

Thought the movie was overall, really great, and I've seen it 4 times 
so far =D
