Scotland on Sunday is reporting that location scouts for Harry Potter and the Half-Blood Prince have been researching various locations in Scotland for possible filming.  Some of the locations include:

*  Smoo Cave, near Durness, which is 200ft long, 130ft wide, and 50ft tall at its entrance;

*  Clo Mor, near Cape Wrath, which at 921ft, are the highest cliffs on the UK mainland;

*  The arches under Cape Wrath, which contain a string of long caves;

*  Stac Clo Kearvaig, a tower of rock that rises 130ft above the waves near Cape Wrath;

*  The cave at the Whaligoe Steps, which lies in a bay enclosed by two large sea cliffs.

A source at the public film development agency Scottish Screen said, "We would be happy to have them here.  It would be a real boost for film-making."  Warner Bros. would not comment, but Scotland is thought to be in contention with locations in Ireland and New Zealand for the sixth film in the Harry Potter franchise which is scheduled to begin filming later this year for a November 2008 release.
