London’s 40th international mime festival opens today. Helen Lannaghan, co-director of the London International Mime Festival, says audiences want "something different". Toby Sedgwick is a movement director, actor, and choreographer. He is probably best known for directing the horse movements in the stage production of War Horse. He argues that mime "releases the audiences imagination" in a way that drama can't. (Image: Mime artists Credit: EPA).
