You'd be forgiven for thinking someone's spiked the water if you see yellow cabs, unfamiliar shop fronts and American street signs in Glasgow in the next few weeks – but it's all being done for the shoot of World War Z .

Glasgow city 🎀centre is being made up to look like Philadelphia and Brad Pitt is heading into town to film additional footage for the zombie thriller.

World War Z shoots from 15-31 August and a spokesperson for Glasgow City Council🦂 told the BBC the local economy could bene𝓰fit by more than £2m.

Glasgow Film Office said it had secured the production thanks to🦹 the city's grid system and wide streets, which are similar to ꦦUS cities.

“The positive feedback and support we are getting from all corners together with a real buzz of excitement around the city is terrific,” the film's location manager Michael Harm told The Hollywood Reporter .

“We had 7,000 peopl🅺e attending the open casting for background artists.”

The film is based on Max Brooks' post-apocalyptic novel World War Z: An Oral History Of The Zombie War and is due to be released next year.
