Filming for the sixth Harry Potter film continued this past weekend. Lochaber News is reporting
that 100 students from Lochaber High School in Fort William filled in as "apprentice witches and warlocks" for scenes involving the Hogwarts Express.
The article goes on to say that filming has begun again in Glencoe, Glenfinnan and Glenspean to help ensure the continuity with the previous films. But for the first time, however, cameras have been shooting at Loch Arkaig (most likely for the cave scene).
"An airborne film unit, and cameramen aboard a fish farm boat have been shooting computer-enhanced sequences, above and on the loch."
Thanks to everyone who sent this in!
