he ultimately had to drop out due to scheduling conflicts. Also in August, filming was set to take place along a road on the perimeter of the Grangemouth Refinery in Grangemouth, Scotland, the location chosen for the length of the road, which was crucial to the shot. A few days later, Paramount announced the film would be released on December 21, 2012. Later in the same month, filming began in Glasgow. The location manager for the film said Glasgow had been chosen because of its architecture, wide roads, and grid layout. Scenes were also filmed aboard the Royal Fleet Auxiliary ship RFA Argus, before the Glasgow shoot.

He was brought in as a new set of eyes not burdened by all the history of the script and said: "[Brad Pitt] took me through how excited he was when he read the book, what was exciting for him, the geopolitical aspect of it. But when we started working on the script,
