AICN have been sent two separate pieces of info stating that Ridley Scott and co will be heading to Scotland in August to shoot scenes for Prometheus.

"ALIENS are to invade the Highlands - after secret plans were hatched to film a prequel to the sci-fiblockbuster trilogy in Scotland.
Location scouts for the long-awaited movie, with original Alien director Ridley Scott in charge, have already visited Inverness and Fort William."
"All cast members had to sign secrecy clauses and were made to read the script in Ridley Scott's Hollywood office. And when Kate Dickie, 39, needed to see the screenplay in Glasgow a security courier flew to Scotland and stood guard over her for two hours.
But the cat was let out of the bag when the film-makers asked about accommodation in Inverness and surrounding towns during August.
They are looking for rooms to sleep a cast and crew of at least 150 people.
While other mountainous parts of Europe have also been considered, the Scottish Highlands backdrop is favoured because it fits the new film's central theme of "grand mythology and universe" in which this original story takes place.
Mediacom, whose film travel and accommodation office is based at Pinewood Studios in Buckinghamshire, would confirm only that a "large feature film" was due to shoot in the Highlands from early August until September, then elsewhere in Europe in October and November."
They also received a report outlining info from The Scottish Daily Express stating that they would be filming in the highlands August through September. Some photos of the (possible) locations of Rannoch Moor were attached..
Pretty epic shots. Nothing official on this yet, but it would seem to be legit. Get yourself to bonny Scotland in August to catch a glimpse of Mr Scott and his hugely impressive cast.
