Revealing mistake: Right at the beginning of the film "rain" is falling on the car the camera shows before it moves to focus into the tunnel. However, look at the cars behind it, they aren't wet at all and it's visibly sunny. It's water being poured onto the car directly in front of the camera.
Revealing mistake: The theatre that is blown-up is supposed to be the Albury Theatre, which was actually renamed the Noel Coward in 2006, and is on St Martin's Lane. The exterior distance shot shows that it is the Gielgud Theatre on Shaftesbury Avenue that is blown-up.
