For the past week or so Glasgow city centre has been turned into Philadelphia for the filming of World War Z, starring Brad Pitt.
It's strange to see Glasgow's streets full of yellow taxis, newstands and even a hot dog vendor in George Square.
It has been causing a lot of excitement (not every day Brad comes to town) and lots of people are around to have a look and take photos. There's a Flickr group collecting them.
According to the steward I was speaking to, not every is happy about the disruption it's causing, but I thought it was great. It's funny how a single sign can make you feel like you're in another country.
Brad has finished his bit now but filming is carrying on until Wednesday next week. It's definitely worth going in for a look if you haven't seen it already.
