Filming HP in Oxford?

[Blaise]

No: HPFGUIDX 3992

Perhaps Simon or someone who knows about the movie can confirm this, 
but I've heard a rumour that they're going to be filming the movie at 
Christ Church College here in Oxford this weekend.  Is it true?  I 
don't really know Christ Church all that well, but the front quad is 
very impressive and it has lots of towers and suchlike, so it could 
look like Hogwarts with a bit of tweaking of the pictures.  Can 
anyone confirm or deny this for me before I waste my weekend 
wandering around looking for a film site?    

-Blaise.
