First idea...

I have one idea for my film intro but I'm don't know if I'll use it yet because it might not work..
Starts off in a dark room, a shed? The music playing is a song called beside you in time by a band called nine inch nails, which is really repetitive and atmospheric.

A man is sitting down with his head in his hands, the camera is looking up at him. He's really paranoid and his thoughts keep flashing up. Has lived in this dark room for years and needs to escape. Signs that he has lived here for ages are around the room, like a mattress on the floor etc. He has done something in the past that has gradually been turning him mad, pictures from this moment flash up sometimes but the whole story is revealed later in the film. What he's done isn't entirely clear... The plot is his escape from this dark room he’s created for himself. About 3 quarters of the way through the intro the music gets brighter and the man opens a window in the room letting the light shine in. He opens the door and stands outside looking up at the sky; he starts to run and the intro ends, screen fades to black.
