Enlightenment?

I was particularly interested in the role of light in Rear Window. Jeffries uses light as a tool and weapon: without it he is powerless. Illumination is an intrinsic factor of film, especially in a voyeuristic genre. For example, the newlywed couple across the courtyard always has their blinds drawn with the light perturbing through. Yes, they’re having sex; but no, we can’t see it. This relates to Keenan’s Windows discourse on the separation of public and private. Moving on, light is also used as a weapon in the penultimate scene of the movie when Jeffries uses his flash to slow down his defenestration, caused by Lars Thorweld. The role of light is necessary and intrinsic to voyeurism, both in the conscious and subconscious perceptions of it.
