Hollywood film crews have descended on Northumberland to film the latest blockbuster from the Transformers franchise.
Scenes from the sci-fi epic - Transformers: The Last Knight are being filmed in Alnwick and Bamburgh.
Around 200 crew members are in Northumberland preparing for filming which is thought to take place later this week and next.
Alnwick Castle will be closed September 15, 16 and 17 due to filming.
The film, directed by Michael Bay, stars Mark Wahlberg as Cade Yeager.It is not clear whether Wahlberg will be in the region for filming.
Councillor Val Tyler said the Hollywood factor is providing a huge boost to the region.
There is no doubt that the spin-offs of such a big budget movie could be enormous and will be felt throughout the local tourism industry and economy. History proved this much when Harry Potter was filmed in Alnwick. At present there are an estimated 200 crew members staying in accommodation in the area and spending money in local shops and restaurants. In the longer run, the film will bring the type of international publicity for the area that no amount of advertising could buy. It is fantastic that they have chosen our beautiful county as a film location.
Filming started in America earlier this year. Crews have also been filming scenes in London.
