When Deborah is in the hospital and Gavin sets the camera up at the foot of the bed, the camera name reads "EX-HOSP-DR-A-CAM". The camera then changes to an overhead camera, which still displays the same camera name. Once the video cuts forward a few minutes, the camera name is corrected to "EX-HOSP-DR-B-CAM"

The priest states that the Catholic church no longer does exorcisms when in real life they do in select circumstances.

Although the missing paediatrician Desjardin has a French name and is said to have possibly returned to Quebec, his name is pronounced by all characters as if he were Spanish (DAYharDEEN, rather than dayJARdan).

The film states that Alzheimer's Disease can be diagnosed almost surely by brain scan, and also the progression of the disease by brain scans. Alzheimer's Disease can only be diagnosed for sure by autopsy after death.

Dr. Nazir pronounces the word "hippocampus" as "hypo-campus" when a real doctor would know it's pronounced just like it's spelled.

When a possessed Deborah is shown trying to consume the cancer girl, the girl's neck "folds" like an accordion, revealing it to be a dummy prop.

At around the 57 minute plus mark when Deborah is supposedly 'restrained' in the hospital bed, the overhead camera shot clearly shows the restraining cuffs are buckled at their widest possible limits. She has her wrist pressed against the far inner side of one and quite frankly in the space that is remaining she could fit a leg or two.

The sheriff follows Deb to a mine after she leaves the hospital, knowing that Deb has already seriously injured a security guard, but allows Sarah and the students to tag along. Very unlikely a responsible sheriff would allow people to put themselves at risk in that way.

Cara's father is at the hospital when she is abducted but apparently takes no part in the search for her.

While the sheriff follows Deb in the forest along the river toward the end of the movie, she carries no flashlight and relies on Mia's camera light to illuminate everything for her. No police officer would ever follow a suspect into a dark forest without a flashlight and rely solely on the light of a camera she's not even holding.

Throughout the movie, the Static effect (visual and audio) is used over and over, but in digital equipment, this wouldn't occur.

The nurse who examines Deborah in the hospital puts her stethoscope on backwards (with the ear pieces facing backwards rather than forwards).

The late night nurse that checks on sleeping Deborah, besides putting her stethoscope on backwards, places it over her heart to listen to her heartbeat when there is a machine clearly beeping out her heartbeat. If she was checking her breathing she would have placed it away from the heart.
