DEMONS

I don't know how I came across it but I was reading up on and then eventually sitting through 'Repo! The Genetic Opera', a horror/rock opera musical film that came out in 2008. It's opening was tiny, only showing on 7 screens in the US but quickly became a cult film. Oh, it was directed by the same guy who did the Saw films.
The plot revolves around how in the future the world suffers an organ failure epidemic; everyone is dying and no-one can afford the transplant operations. However, GeneCo, a multi-billion dollar biotech company come up with the agreement that they will finance your transplant, so long as you eventually repay the money. Clients who are behind on payments willl suffer the wrath of the Organ Repo Man - a man legally hired to claim back what belongs to GeneCo. The twist in the story is that Repo Man has, in fact, got a heart. He lost his wife at the birth of his daughter and promised to protect her from the devastating world she had been brought in to. Naturally, the best way to do that is to plant a blood disease in her system so she has to stay indoors at all times. 17 years have now passed and his little girl, Shilo, still doesn't know the truth - until she has an encounter with her mother's old best friend, a blind opera singer, thus quenching her thirst for freedom and, obviously, the truth. There is loads of singing going on at all times as well. The cast is reasonably well known: Paul Sorvino, Paris Hilton, Alexa Vega, Anthony Head and Sarah Brightman.
Anyhow, the costumes and the makeup are really quite awesome:
