The Unborn

Although Casey is shown following and reiterating Sofi's instructions to destroy all of the mirrors in the house and then burn all remaining pieces of them, when Romy enters the home a few scenes later, the mirror over the mantle is shown with sizeable pieces remaining.

The contact lenses used to give the "heterochromia" effect are incredibly obvious.

The blue sections cast shadows on the brown iris below.

The photo that shows the main characters uncle is a Polaroid, however Polaroids weren't invented until 1948.

Her grandmother, Sofi says he died in 1944 in Auschwitz.

At the ending scene, when Casey runs on the bridge, the surface of the road seems to be dry, but in the next scene, it is wet.

(at around 1 min) Casey is using her laptop on her bed, she closes it and leaves it sit, then she turns off the lamp and climbs into bed and the laptop is gone, you see a light spot in the bed that could have possibly been it, but later when she awakes from a nightmare the computer is definitely not there.

When Casey is surprised by the "visitor" in her medicine cabinet and is on the floor, she leans against the door and the toilet behind her shifts indicating that it is a prop toilet, not bolted down as it should be.

When Romy hits the boy with her car, she closes the door when she runs to check if he's okay.

When she runs to get in her car, the door is open.

In the link between the movie reel and nightclub scenes a train is shown going past in reverse.

The audio is convincing, however the headlights on the train give it away.

The cars under the bridge are also in reverse.

In the club scene, after entering Mark asks Casey, Romy and one other girl if he can get any a drink from the bar.

Romy and the other girl orders a drink.

Casey says no.

As soon as Mark walks away to complete the order, Casey begins to walk through the club already holding a drink.

When Romy chats with Casey via webcam, the light on the webcam on her MacBook is off, but it should to be on.

The librarian who shows Casey the copy of the antique "Book of Mirrors" simply requests that she "Please exercise care when handling the manuscript.

" In fact such manuscripts are never allowed to be handled without cotton gloves - though Casey is subsequently shown to be turning pages with her bare hands.

In one of the scenes where Casey is hearing noises coming from the mirror in her bathroom the camera shot is shooting right through the open bathroom door into the mirror, yet the mirror shows the reflection of a closed bathroom door.

When the professor lecturing is shown far away the word "Before" on the chalkboard behind him is completely underlined.

Next time the professor is shown in his closeup, only part of the word, "Befor" is underlined.

The letter "e" is clearly NOT underlined.

Then afterward, he is shown in a blurry mid-shot, the word "Before" is completely underlined once again.

In the opening scene, there is an overhead of a woman jogging on a bridge with snow plowed off to the side.

They immediately cut to a ground-level shot, and all of the snow is melted but the bridge is quite wet.

The librarian refers to the Sefer ha-Marot as a manuscript when she hands it to Casey.

However, the illustrations appear to be printed, not hand drawn.

When Casey gives the Book of Mirrors to Rabbi Sendak, he places it on his desk in front of him, with the front cover facing up and the spine on the left like any normal book.

But the book is in Hebrew, which reads from right to left, so that the pages are turned from left to right while reading - the reverse of books in European languages.

So the face-up closed position for the book would be with the spine on the right - and a Talmudic scholar would automatically set down a book facing this way.
