What Lies Beneath is a 2000 American supernatural horror-thriller film directed by Robert Zemeckis. It stars Harrison Ford and Michelle Pfeiffer as Norman and Claire Spencer, a couple with a seemingly perfect marriage who experience a strange and terrifying haunting that uncovers secrets about their past and seems to threaten their lives.
This film contains examples of:
Ax-Crazy: Norman, once everything is out in the open.
Bittersweet Ending: Madison gets her vengeance by killing Norman and is able to finally move on. Claire is undoubtedly left mentally scarred from everything that's happened, but her visit to Madison's grave seems to imply that she's making steps towards getting on with her life.
Dangerous Key Fumble: Claire fumbles with the keys when escaping from the house towards the end, giving Norman just enough time to hitch a ride without her noticing.
Dark Secret: Norman isn't quite the perfect husband Claire thinks he is...
Demonic Possession: Claire allows herself to be possessed by Madison, which allows her to find out the truth about the affair. She later inadvertently allows another possession as Norman attempts to drown her.
Domestic Abuser: Subverted. Warren Feur initially comes across like this, but it's all a misunderstanding.
Driven to Suicide: Norman claims Madison killed herself when he tried to break off their affair. He's lying. He also intends to make Claire's death look like this as well.
Eye Awaken: Unconscious Norman's eyes fly open as Claire makes her escape from the house during the climax.
Foreshadowing: Claire having a car accident prior to the events of the film is mentioned a few times. It turns out she had the accident after driving off in a heartbroken rage after discovering Norman's affair, and the accident left her unable to remember the affair - until Madison makes her remember.
Freeze-Frame Bonus: Madison is briefly seen reflected in the bath water for a second time (during the "YOU KNOW") scene. She only appears for about a second. Another example occurs at the very end of the film: as the camera pans down and the screen fades to black, an image of Madison's face can be seen in the snow.
Ghostly Goals: A combination of both Type A and a little bit of Type B: Madison wants to exact revenge on Norman, but also leaves clues for Claire to lead her towards the truth.
Go Out with a Smile: Madison's spirit, having avenged her own death, gives a small, peaceful smile as she floats through the lake.
The first time Claire's face morphs into that of Madison's is jarring enough. The second time it happens - when Claire's face suddenly morphs into Madison's very dead, very decomposing face - is downright horrifying.
Karmic Death: Norman is killed in the same way he murdered Madison - via drowning. Not only that, but he dies in the same lake in which he disposed of her body.
Oh Crap: A particularly chilling version happens towards the end, when Claire realises that Norman most certainly did not dial 911. Later, during the climax, Norman has one when the very dead Madison tilts her head towards him.
