Brad Pitt and his family arrived in Glasgow by train on Tuesday along with other cast and crew to continue filming his new movie World War Z.
Parts of the city centre will double for Philadelphia where the zombie film is set.
American street signs and traffic lights have been put up on streets in the Merchant City area, where the two-week shoot will take place.
Vending machines selling US newspapers have been dotted around and the streets are lined with yellow taxis, Philadelphia police cars and other vehicles, including tanks.
Glasgow City Council said the production will involve almost 1,200 people when on location and the impact on the local economy is likely to be in excess of £2 million.
