Harry Potter special effects supervisor Tim Burke talks about HP8!

  A interview with Harry Potter special effects 
supervisor Tim Burke has surfaced online,
thanks to denofgeek.com, 
we have part of the interview here:
"For Part 2, we've done away with Hogwarts,",
said Burke. "It was such a major job to stage 
the battle of Hogwarts,  and we had to do it 
in different stages of production."

"We had shots with complex linking camera moves 
from wide overviews, to flying into windows and interior spaces. 
So, we took the plunge at the end of 2008, and started 
rebuilding the school digitally."

"It's certainly a bold move to rely on an entirely digital Hogwarts,
especially for such a key sequence, 
and it's clearly been a task with its challenges."

"It's taken two years - getting renders out, 
texturing every facet of the building, 
constructing interiors to see through windows, 
building a destruction version of the school."

Do you think a completely digital Hogwarts in the film is a good thing,
Or do you think the old method of combining location filming and digital effects was better?
