Continuity: During the bombardment of the British Consulate, there are several continuity errors, including a self-repairing window and blind situated behind the piano. And it cannot be put down to the nature of the film because several errors have been carefully avoided.

Continuity: About 30 minutes away from the end, Brother Belcher can be seen walking past the gates. Then, when he's 1 yard away from the gates just to make sure it's all clear for him to go, he gets a bullet that flies out of nowhere. When the bullet hits his hat, the hat shoots upward and out of shot. In the wide shot of all the gates and the walls, there is no sign of his hat.

Audio problem: When Sid James comes out of the building, in the scene at the end with the big fight, a man comes up to him and Sid asks, "You wish to see me?" Just before this, you see him mouth the words to that line.
