Awake

Wealthy Clayton Beresford (Christensen), stricken with a heart defect, must undergo a transplant to save his life. Unfortunately, something goes wrong, and he experiences "anesthesia awareness," which means that he appears asleep but is actually awake and fully aware of everything going on during his operation. Rather than build suspense and tension from such an intense premise, the story's twists and surprises (including an absurd-even-by-horror-movie-standards plot for poor Clay to die on the operating table) pile on ad nauseum, and Christensen is expected to carry much of the movie while flat on his back.
