A set, at Dorset's disused Winspit Quarry near Worth Matravers, is for the latest Disney+ Star Wars series, Andor.
The series is a prequel to the 2016 spin-off film Rogue One, and follows main character Cassian Andor.
Filming started in the UK last week with lead actor Diego Luna and stormtroopers spotted on a beach in Cleveleys, Lancashire.
