Shot at the Action Underwater Studios facility in Essex, Louis Ellison directs this extraordinary and unique promo for ambient dubstepper Context.

Louis explains: "As Context is unsigned, we had an absolutely micro budget so we got a great deal for the studio and everyone else worked for free. In fact we had people queueing up to be involved as it was quite a unique project. We were very lucky with the actress we cast as she took to the water marvelously and really grasped what I wanted.

"However, directing a cast underwater was probably one of the hardest things I've ever done. We were shooting through a window and I was speaking to them on a microphone with speakers hooked up under the water. The tank was 20ft deep and they had 2 divers maneuvering them into position and then quickly releasing their air and swimming out of shot when I gave the go ahead.

"The outdoor scenes were shot under a flyover on the coldest night of the year - I believe it was minus 8 that night! To get that last shot of Context in the puddle we left it until the very last thing. Then he got down in it and we poured water all over him! We only had one take to get this and I think it works really well as the closing shot of the video."
