Moral Virtue or Temporal Hedonism? Subtext Within External Narrative
While Eyes Wide Shut has many potential routes that can be explored, I believe this film has a particularly interesting and seldom discussed interpretation when viewed from the subtext of its superficial narrative.
One element of background scenery that is showcased consistently throughout the film makes highly suggestive references to the Garden of Eden.
We can even view the mansion scene as a metaphor for the Garden of Eden, where we see the figure confronting Bill as a representation of Satan (red, about to engage in unbridled hedonism, a token of the temporal world); Bill, refusing to get naked, is expelled from the mansion (Garden of Eden). This alludes to Adam discovering his naked body.
When Bill returns to Alice, she recollects her dream, stating, "we were naked" and "he had to go and find clothes for them", also mentioning that "she was in a beautiful garden". This means that Bill and Alice are our Adam and Eve figures, with the mansion serving as a metaphor for the place of original sin.
The connection between eyes being wide shut and John 9:25: "Where before I was blind, now I can see" is the capacity to see what sin is and the ability to acknowledge it and choose to act accordingly—the path of spiritual development or temporal pleasure. The term fidelio/fidelity (faithfulness to your spouse) references the individual choice to feed temporal hedonism or to nourish spiritual development. Bill and Alice have chosen the former, and this is confirmed in the final dialogue.
As the audience, most of Bill's point of view is contrasted with his surroundings, which are more often than not ostentatious and exuberant. They are fitting allusions to the emptiness of materialism. When Bill enters Domino's apartment, which is presented as squalid, he is uncomfortable. The unkempt nature of the apartment serves to reflect the sordid state of Bill's soul.
The last line by Alice, says, "and you know, there is something very important that we need to do as soon as possible....fuck." What this implies is that Bill and Alice's existential and marital crisis did not lead towards spiritual development, but back toward earthly hedonism.
While their eyes are open to the world around them and to the inherent impropriety of the world, they choose to close their eyes to it, and continue on their destructive path towards pleasure (sex) and temptation (infidelity).
Their eyes are wide shut.
