My first mistake was buying this movie because of Cameron Diaz, and no sooner did I realize my second mistake that the movie just kept dragging on. When a financially troubled couple of Arthur and Norma Lewis (James Marsden and Cameron Diaz respectively) are approached by a stranger who offers them one million dollars, the couple only has one obstacle in the way. They need to press a button inside a box which was left at their doorstep mysteriously. Only when they press it, someone will die. As expected the couple presses the button and a woman is killed instantly in her house. From then onwards the viewer is taken through several mind boggling scenarios one after the other which culminate into the ultimate (read predicted) finale. Not a strong recommendation.
