Awesome Music: Boccherini's Minuet note from String Quintet in E Major, Op. 11, No. 5 , which plays throughout the film.
Crosses the Line Twice: A group of criminals plot to kill an old woman? Not funny. A group of criminals fail miserably at killing an old woman, and end up killing each other? Funny!
Earlier on in the film, Louis does the same thing, causing a close up of the back of Marcus' head as he slowly starts to turn round while a terrifying crescendo starts playing and the other members of the gang, who unlike Louis have worked with Marcus before and know never to do that, look on in horror. Fortunately, before Marcus turns round fully and presumably snaps, Mrs Wilberforce brings them tea.
