Found it on
Wizard City. But it didn't say the original source.
It looks as if they're making the Quidditch match
very wet in PoA and they're doing it the hard way. A large order of thermal suits from Reed Chill Cheater has just been completed to keep the stars nice and warm while filming the Quidditch scene where visibility is impossible and Harry loses his very first match (that he's actually present for).
Sounds as if it's going to be a very effective scene, not bad seeing as we all thought there wouldn't be any Quidditch at all.
