In the 35th minute Camila is shown with blood on the top of her white undershirt. It is unclear how and when the victim's blood got there.
In the 68th minute, Dermot is on the stretcher with the headboard raised, hence his head is at an angle. Yet in the shots of Camilla, from behind, speaking with Austin, Dermot's face is shown flat, facing upward.
In the 88th minute when the nurse confronts Gerry about the drugs he has stolen, he shoves her. In the next shot she is clearly falling straight downward, not backward.
Gerry could not have drawn a full bag of Camila's blood as fast as he does. She would have become dizzy, passed out or possibly have gone into shock.
The blood on Dermot looks unrealistic, almost pink.
In the 71st minute when Austin gets into the back of the ambulance, one hears two loud slams which are presumably him closing the back doors. They sound almost like gunshots. When Gerry enters the driver seat and closes his door, it sounds like a normal slam of a vehicle's passenger door. The back doors would and should sound exactly the same.
In the final minutes, H52 is not a valid license plate number for a police, or other vehicle.
The ambulance dispatcher is on the phone with the nurse who saw Gerry steal the drugs, and then was assaulted by him. There is no reason the dispatcher wouldn't immediately call police, as in fact the nurse should have done earlier.
When the detective enters the convenience store, one sees posters for Molson Export and Molson Dry, Canadian beers. While set in Philadelphia, the Canadian movie was filmed entirely in the province of Quebec.
In the 32nd minute Camila advises Dermot that he has to "push past the pain" for her to perform the procedure, yet he has already been given morphine.
In the warehouse when Austin loses his gun to Gerry, within seconds, Austin retrieves a small scalpel from the top of the medical bag. He would not have known it would be there, nor could he retrieve it so quickly without knowing its exact whereabouts.
