Continuity mistake: When the kid's mother puts her hand against the glass and steps back, she gets hit by the car and just AFTER she is hit, the brakes are applied. Then when they switch to when Ed is driving the lady, he slams the brakes on BEFORE she is hit, as if he saw her first.
Continuity mistake: In the first minute or so of the first scene, the doctor, played by Alfred Molina, is writing notes about his patient. He writes the word evil. The movie shows ev connected as in a lazy type of cursive from the left side of the doctors hand, then switches to a view from the right of his hand. The ev is now unconnected written in non-cursive writing.
Continuity mistake: At the beginning, just after Ed has hit the woman, he gets out to help and the husband is lying down next to her. When he says to Ed, "What have you done," his left hand is on Ed's jacket then puts it down to his wife, but in the next shot it is back tugging on Ed's jacket.
Continuity mistake: In the middle of the film just after Ed walks outside after taking photos of the dead husband, he calls Rhodes, then spots Larry across the way. Watch closely in one shot, we see Ed pass Rhodes, and in the very next shot he is some distance from Rhodes having just passed him in the previous shot.
Continuity mistake: When Ed breaks the limo window with a crowbar to get the phone from the actress, Ed runs and picks it up in his left hand, but in the next shot it is in his right. Also, when he smashes the window, there is a small piece of glass at the top and a very jagged bit left at the bottom from Ed's POV, when it cuts to inside the limo they are gone. He also reaches inside the car twice.
Continuity mistake: When Paris is talking to the innkeeper about the orange grove she is buying in Florida, the strap of her purse keeps changing places. Sometimes it is lying over her coat and other times her coat is more open and it is lying across her tee shirt. It goes back and forth throughout the scene.
Continuity mistake: When Ed the hotel manager and Rhodes discover the actress' body, they go rushing to room 10. When Rhodes enters the bathroom where he left the convict, Ed is standing behind him with his right arm by his side, yet in the following shot from the window, he now has his right hand on the bathroom doorframe.
