Orphan

When Esther is introduced to her new class, she is holding a Nelson Spelling book.

These books are not used in the United States, where the film is set; they are, however, used in Canada, where filming took place.

When Daniel is playing Guitar Hero on his Xbox 360 console, his controller power light is not on, indicating the controller is not on/or plugged in to the console.

Also, when the game is shown on the television Daniel is playing on the 'Expert' difficulty and appears to be doing quite well, however looking at his fingers, Daniel is only pushing the first three buttons on the guitar (easy mode) and not all five buttons as Expert mode requires.

Early in the film, at one point, the family returns home and it is snowing lightly.

The windshield wipers stop and there is a brief overhead shot of Kate near the car with a lot of snow collected on the windshield.

Not enough time had passed to allow that much snow to collect on the car.

When Esther catches John and Kate having sex in the kitchen, the reflection of the couple in the glass shows John holding Kate against the counter with one arm.

In the same shot Johns arm is not holding her down.

Also, as John turns his head away from the glass, his face can still be seen in his reflection.

The reflection appears to have been added in post production.

When Kate climbs out of the ice hole in the pond, she is wet and her hair is wet when she picks up Max.

But when there is a close up of her kissing Max, Kate's hair is dry.

Her hair is wet again in the next distance shot.

The Smith & Wesson m-36 holds 5 rounds, as clearly shown when she removes it from the safe and opens the cylinder.

Esther fires five rounds when chasing Kate through the house.

When Max picks it up by the pond, she fires a "magical" sixth round.

Later on in the movie, Esther has blood and makeup on her face, but in the close up shot, her face is perfectly normal, when the shot turns back to normal her face is covered in makeup again.

When Kate is shopping in the grocery store with Esther and Max , Sister Abigail calls Kate on her cell phone.

As the camera cuts between Esther and Kate, the produce display changes without the cart moving.

The hospital documents shown from the Saarne Institute when Dr.

Varana is speaking with Kate on the phone are printed and written in English rather than Estonian, where the hospital is located.

When Kate and John first meet Esther and speak to her while she paints lion cubs, her painting progresses a lot quicker than it should for the amount of time that passes on screen.

When Kate drops the kids off for school, her vehicle is parked on a slant.

She should have known without a doubt that the car was tampered with because the car would have immediately rolled backwards before she exited the vehicle if the vehicle was not in park.

When Esther tries to kill Danny in the hospital, the ECG (green curve) and oxygen (blue curve) alarm only go off after she puts the oxygen sensor back on Danny's finger.

However, the ECG is not monitored using the oxygen sensor, so the ECG alarm should have gone off as soon as she started to suffocate Danny.

When John opens the fish tank and sees the images on the wall the light goes across all the walls, however the light is not strong enough to give off that much light.

Fish also do not use blacklights.

When Kate hits Esther in the hospital her cellphone falls on the carpeting (part of floor is covered carpeting).

But in next close-up the cellphone lies on the naked floor far from carpeting.

(at around 1h 55 mins) In the credits the word "Russia" in Russian from Esther's papers is spelled wrong.

The first letter should look like the Latin character "P," not "R" as was shown in the film.

Cyrill P is Latin R.

CPPP = S.

After Kate enters "antisocial personality disorder" into an Internet search on her computer, as reflected in her glasses lenses, the screen immediately directs to a synopsis page clearly labeled with a different personality disorder, Borderline Personality Disorder.

The two disorders are not synonymous.
