Brittany Murphy's lips change color, from furious red to natural, and back again, from scene to scene.
While Mary is sitting in the psychiatrist office she has on purple stud earrings in both ears. She walks out of the room and goes to sit in a chair alone and suddenly she has on no earrings at all.
Around 16 and a half minutes into the feature, Mary (Brittany Murphy) speaks with the receptionist. During their back and forth cuts, a security guard can be seen walking in the background from numerous directions that make no sense in continuity.
Throughout the movie Mary's upper body outfit is not consistent. One minute she will have a white undershirt on and A few seconds later the white undershirt is gone. This happens all throughout the movie..
After Mary is hit by the car and she is being kept in the ICU, she should have all kinds of wires attached to her body to monitor her heart, respiration, BP, etc. She had none of those; only a neck brace and IV.
Dean Cain's stunt double for when he's s clinging on to the pipes towards the end of the movie is much smaller than Dean Cain.
The hospital is about to close down for renovations on Saturday and is not accepting new patients yet the doctors want to keep Mary for 72 hours.
