Continuity mistake: When Regan and Bianca first jump on the bus to escape the hitmen you can see through the windows that there are only six people on the lower deck, but when the scene changes to inside the bus all the seats are full. (01:00:24)
Continuity mistake: The bus stops, and the hitmen are behind it in the blue Volvo estate; a white car stops behind the Volvo. When Regan and Bianca get off the bus there are no cars behind the blue Volvo, the angle changes and the white car is back, and the hitman shouts out of the passenger window for the driver of the white car to back off.
