A smiling Brad Pitt has been seen waving to fans in the Scottish city of Glasgow as he left the set of his latest movie World War Z.
The US actor was in town this week to shoot the zombie horror movie, which is based on a book by Max Brooks.
Paramount film studio has made every effort to keep the movie under wraps.
The set is closed to all media and no production details have been released.
The centre of Glasgow has been transformed to depict Philadelphia in the aftermath of a war between humans and zombies. Shooting is expected to last two weeks.
