The first full-length trailer for Brad Pitt’s much-anticipated zombie film, World War Z, has been unveiled.

The two-and-a-half minute trailer showcases scenes which were filmed in Glasgow for the up-coming blockbuster, including a lorry crashing into parked cars and a terrified crowd being chased through George Square.

It also includes glimpses of dramatic set-pieces featuring a tidal-wave of zombies and a countdown that shows the world’s population dropping by the billion.

Glasgow was transformed into Philadelphia for the zombie film, which was shot in the city in August 2011.

Pitt plays United Nations worker Gerry Lane in the film, which features an outbreak of a plague that turns people into crazed monsters. It is based on the novel World War Z by Max Brooks.

The film had originally been scheduled for release in December, however, re-shoots mean it is now set to hit cinemas in June 2013.
