At one point, Jane says she must call New York, but Ben says it's 3am there, yesterday. This is a mistake. If it was 3am in New York, in Tokyo it would be 4pm in the afternoon on the same day (give or take an hour for differences in daylight savings).
The morning after the road accident, Benjamin and Jane are taking pictures of themselves outside. Benjamin is on our RIGHT hand side with Jane on our LEFT. A few minutes later, the pictures are shown to us. Benjamin is now shown on our LEFT with Jane on our RIGHT.

Q
Why did Ben attempt to electrocute himself?
A
He wasn't trying to electrocute himself. He was trying to get Megumi off of his shoulders. He remembered what the old man said about spirits being light. His logic: Megumi is light/electricity so that is what can kill her.
Q
Is it true that watching "Shutter" can bring on epileptic seizures?
A
While no seizures have yet been reported, seizure-prone individuals should be aware that there are instances of flashing lights, maybe 30 seconds apart.
