Here is a little bit of news for everyone.Leavesden studios, aka: Harry Potter studios, are running out of room building the new sets for The Goblet of Fire.
As you may guess they will be building hedges for the giant maze sequence in the Tri-Wizard tournament.The surprise is that they are building the giant hedge maze at PINEWOOD STUDIOS England, quite a switch from the normal routine.
As for the underwater sequences we are just waiting to confirm, there's only 1 studio in the UK with the facilities, Shepperton studios, so we shall have to wait to see. We'll bring you more as we get it.
