''Shutter'' is a 2004 Thai horror film by Banjong Pisanthanakun and Parkpoom Wongpoom. It focuses a on young couple, Tun and Jane, who, after being involved in a hit-and-run accident, find themselves menaced by the ghost of a young woman named Natre, most prominently in mysterious and ghostly images seen in [[CameraFiend photographer Tun's]] developed pictures. As Tun's circle of friends start to kill themselves one by one, it soon becomes clear that there is a lot more to these images and hauntings than meets the eye - and Tun himself is hiding many dark secrets...

The film was [[ForeignRemake remade]] in 2007 as a Tamil film called ''Sivi'', and as a 2008 American film, also titled ''Shutter''.

%%* RapeIsASpecialKindOfEvil
* TheReveal: This film contains several, all centering around Natre. As it turns out, [[spoiler:Natre was not killed in the hit-and-run accident - she had been dead a long time prior to that. She had, in fact, committed suicide. So, why is she seeking revenge, if she wasn't killed in a hit-and-run? Well, it turns out that Tun went to college with her, and started dating her. Natre fell deeply in love with him, but Tun kept their relationship a secret, even from his closest friends, due to everyone else finding the quiet, unassuming Natre to be "weird". He didn't love her, although he did care about her a lot. However, Natre fell into a deep depression and became suicidal, and shortly after that, Tun dumped her.]] Then, towards the end of the film, the entire truth is revealed: [[spoiler:Natre became depressed and eventually killed herself because of Tun's friends holding her down and raping her one night. To add insult to injury, when Tun walked in on them, instead of helping her, chose to protect his friends instead by providing photos of Natre to his friends so that they could use them against her.]] Then, near the very end of the film, the reasons for [[spoiler:Tun's neck ache and increased weight are revealed: Natre's spirit has been sitting on his shoulders the whole time, something which is only revealed when he takes a picture of himself]].
