Sienna Miller stars in The Hours' new video for single "See The Light", which has premiered on their MySpace page ahead of its release date of 8 December. The Hours singer Ant Genn has explained: "It's a song about struggle and addiction and fear and darkness", and Sienna's performance certainly fits that bill, as she rubs her hands in cows' blood after being trapped in a Prada store dressed in a hospital patient's gown. The short film is codirected by Damien Hirst, whose artwork Sienna entered a pre-sale bid for just a few weeks ago. Check out the video below and let me know what you think: do you love it, or would you rather leave it?
