Continuity mistake: In the scene where Ali is changed to the railings, his pants are down. A middle-aged woman comes over and hits his manhood. Obviously he is naked from the waist-down, but in the scene straight after you can just about see Ali's trousers at the bottom of the screen.
Continuity mistake: When Ali and David fight, the alignment of the gun put onto the desk changes between shots.

Continuity mistake: In the scene where Ali walks to the floor of the House of Commons, he walks past Charles Dance and Michael Gambon and they say something like "What is he doing..."

Continuity mistake: When the PM shows Ali the red button, the alignment of the newspapers on his desk changes between shots.
