Looking at the use of close up and high contrast shots
Almost all the shots in the film are compromised of close up facial shots - expression mutating naturally - close up shots of lips speaking etc.
Scenes take place in very similar, blank setting - focus is on emotion/facial expression
Facial expression/high contrast imagery especially important as the film is silent and therefore all emotion must be conveyed through the face alone - heightened emotional responses
A few dialogue inserts to convey plot
