Filming of Hollywood blockbuster World War Z starring American actor Brad Pitt will result in a number of street closures over the weekend.

The A905 (Wholeflats Road) in Grangemouth will be closed from 20:00 BST on Saturday until 07:00 on Monday.

In Glasgow, George Square will be shut on Sunday and there will be restricted pedestrian and vehicle access around the area throughout the weekend.

The public is also being warned of limited opportunities to see filming.

A statement from Glasgow City Council said: "Pedestrian access on George Square will be limited this weekend as the production will use most of the square.

"People considering coming to the centre of Glasgow over the weekend to see the production should be aware that there will be very limited opportunities to watch filming.

We recognise that there may be significant local interest in this filming taking place and would urge members of the public to take extra care Insp Ian Scott, Central Scotland Police

"In addition, people who do come to the square may be asked to move on or stop by stewards to allow filming to take place."

A cast and crew of 1,200 has been shooting scenes in Glasgow since Wednesday. More filming for the movie will take place in the city until 31 August.

American cars, street lights and signage have been brought in to resemble Philadelphia, the film's setting.

Work on the Paramount Pictures movie, which is based on the Max Brooks novel World War Z: An Oral History of the Zombie War, has already taken place in Valletta in Malta and in Cornwall.

Falkirk Council said that it would be closing Wholeflats Road, between the Wholeflats Roundabout at Grange Road as far as the Inveravon Roundabout (at the junction of the A904) on Saturday evening.

In addition, there will be no access to or from Wholeflats Road, from the Jinkabout Bridge, as well as from and to Inveravon Rd.

Insp Ian Scott from Central Scotland Police said: "We recognise that there may be significant local interest in this filming taking place and would urge members of the public to take extra care on the roads and for drivers to be aware there may be pedestrians in the area."

The film crew is scheduled to be in Scotland until 31 August and Glasgow Council said that the deal to use the city was likely to generate in excess of £2m to the local economy.
