Question

Why was the movie shutter called shutter?

Answer 1

Sorry, I can't tell you!

But that movie was really bad!

Answer 2

It is referring to the shutter of a camera.

Answer 3

because it was all about photography

Answer 4

because all the men in that movie, the 3, are all photographers, and they all ganged up on the girl and killed her.

Answer 5

because of the use of a camera

That's when the ghost showed up, when they used the camera.

There's a shutter on the lens of old cameras

I figured that out from the previews, Never saw the movie.

So I'm sorry if I'm wrong, anybody who has seen it feel free to correct me

EDIT: I was right.............

Ben and his new wife Jane leave New York for Tokyo, Japan, where Ben has a job as a photographer. They start to find mysterious lights in their photos. Ben's assistant takes them to her ex-boyfriend, who says that the lights are spirits and then finding a mysterious presence stalking them. They then go to a psychic, Murase; however, Ben refuses to translate what Murase says.
