- Alternative Character Interpretation: Is Stéphane a bored day-dreamer, or mentally ill? The beginning implies that his behavior is a result of trying to cope with his father's death from Cancer, but doesn't state whether this kicked off his issues or simply exacerbated them.
- Hollywood Homely: Charlotte Gainsbourg plays the plain woman whom Stéphane initially ignores in favor of her more attractive roommate.
- What Do You Mean, It Wasn't Made on Drugs?: Since the film is about dreams, this was probably intentional.
