Once again HP4U has posted a report of a visit to the set of Harry Potter and the Goblet of Fire and of having a tour of the Quidditch World Cup campsite, the Great Hall, the graveyard, Dumbledore's study and watching a fluffy white ferret being put into a carrying case.
From the report:
However to their great delight the assistant director said they could sneak into the graveyard to watch for a few moments. It was all so impressive and the Graveyard is vast, creepy and enchanted and soooo realistic. Every tombstone and stone coffin were hand covered in moss and lichen, mist swirled around the entrance to what one of the crew said was a charnel house. There were giant trees and bushes twisted into tortured shapes. Not a place anyone would want to be at night. Because the grass is real and the entire floor is sculpted and turfed it also smelled like you'd imagine a gloomy graveyard would. The heat from the lights and the amount of bodies (live ones) made the place so warm that steam was rising from the grass making the place seem even more scary.
