At its core, "Eyes Wide Shut" is a film about the performance of identity. Dr. Bill Harford is a man who appears to have it all – a beautiful wife, a successful career, and a comfortable life. However, as the film progresses, it becomes clear that his identity is a fragile construct, threatened by the desires and secrets of those around him. Bill's journey is a metaphor for the fragility of human identity and the ways in which we present ourselves to the world.
