Corrected entry: When Teddy's wife walks over to the window and looks out onto the lake and the sunset, she is talking to Teddy. The shot switches to see her face where she is still talking. Then the shot switches back to Teddy's point of view and we see her turning around. The audio still has her talking, but her mouth isn't moving as she turns.SamaraEsther

Corrected entry: In the flashback of Teddy where he is staring at the dying German officer who tried to commit suicide, the camera shows (from the gun's perspective) as the officer reaches for the gun. On his hand he wears a wedding band, but in Germany the wedding band is worn on the right hand.
Corrected entry: Edward has several flashbacks to being one of the soldiers who liberated Dachau. Many of these show piles of bodies encased in ice and heavy falling snow.

Corrected entry: When Edward meets with Rachel in the cave, she talks about "Sodium Amytal, an opium-derived sedative". Sodium Amytal is a barbiturate which has no chemical relation to opium.
