According to the Vancouver Sun,
“Several dozen students and fans gathered at David Thompson secondary in Vancouver Tuesday hoping a for a glimpse of the stars on the set of Twilight: New Moon. They were not disappointed. A few lucky Twilighters saw series author Stephenie Meyer beyond the barricades set up outside the school cafeteria where filming is taking place.”
The filming at seemed to go off without a hitch. The crowd outside was orderly and didn’t cause any serious problem for the Vancouver police officer who was onsite. Unsurprisingly, given the plot, Robert Pattinson wasn’t on set.
