The first big-name actor have been spotted on the set of future blockbuster 1917 in Glasgow.
Kingsman actor Mark Strong and Captain Fantastic star George MacKay have been spotted working with director Sam Mendes at the old dockyards in Govan.
Skyfall filmmaker Mendes, who won the best direction of a play prize for The Ferryman at the Tony Awards on Sunday, was seen watching footage on a monitor and in conversation with Oscar-winning cinematographer Roger Deakins.
Strong and MacKay were in full costume, shooting scenes next to World War I era vehicles.
Very little is known about the plot of the film but the assembled actors were all pictured in military uniforms, many with rifles slung over their shoulder.
The film is also due to star Benedict Cumberbatch, Andrew Scott, Colin Firth and Richard Madden.
