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..." Look at the guy next to Charles Dance, he has his right hand on his face but immediately in the next shot he is gesturing with it and waving papers with the other hand.David Mercier
Continuity mistake: In the scene where Ali is at the center with the kids, he gives some yellow stickers to one of them and the kid sticks them to his arm. But in the next few shots the stickers keep changing their position on the kid's arm.
