A young man sits alone in his flat, he appears trapped, contained, waiting for something until there is a knock at the door...

Like his acclaimed TV promo for Luther last year, Caswell Coggins' new film Knock At The Door is rich in explosive movement.

This is a short dance film featuring dancer and co-choreographer Anthony Missen, from Manchester-based dance company, Company Chameleon - with music by Mean Red - created as part of the C4 Random Acts series. But it's just as much about the atmospheric direction and stunning camerawork (by Deane Thrussell) as the choreography.

The film is one of a series of three dance based films, the second and third shoot in March and will feature dancers from the dance company,The Ballet Boyz.
