Torture/Snuff film at the beginning question - SPOILERS
SPOILERS -
The film is him dealing with,the murder and torture of his family?
------------------------------------------------------------------
If it is TRUE that he murdered his wife and "treated his daughter like an animal", I took that that snuff video at the start is from those events. The girl looks young, so it is possible that that is the daughter, but it could be the wife. He is so detatched from what he did that we watches the video of it without recognising what it actually is showing. It is only in his search for "fear" that he unlocks his mind.
From the point of view that the film is his inward journey, then the boundries of what is real and what isn't become blurry, and even non-existant. If the film is largely splintered and viewed from someone with an unhinged mind, then it is possible that the on-film killing of the woman looking for her daughter, who some think is his wife, is just a re-inactment in his mind. I do like the idea that F is a representation of aspect of himself he has neglected. Perhaps she is mixed in with memories of his daughter, since F is also the first letter of her name.
The film is his own distorted view of his wife's murder and abuse of his daughter?
----------------------------------------------------------------------------------
The other interpretation, but much more subjective in many ways, is that the film is his distorted view of the kidnapping of his daughter, and the subsequent murder of his wife. The descent into the underworld is again his own descent into his psyche. This makes the snuff film, just another peice of media he has collected. However, WHERE DID HE GET IT FROM?
All of his media comes from his own cameras, or has been recorded off TV, so just were did he get a film of a girl being tortured and perhaps raped? He implies that it is fictional, but it would be the only fictional peice in his collection. Perhaps he says so because he hasn't accepted the truth, that he has killed his family.
What do you all think?
