Ken McMullen (b. 31 August 1948, Manchester) is an award-winning film director and artist living currently in London. His feature films are distributed worldwide, his documentaries broadcast extensively and his art works exhibited in leading contemporary art galleries in Europe, The United States and the Far East. McMullen's films are grounded in philosophy, history, psychoanalysis and literature. McMullen's exhibition Signatures of the Invisible brought together artists and scientists working at CERN, the European particle physics facility near Geneva. His other work includes filming conversations with leading physicists at Stanford Linear Accelerator Centre, which he describes as "making a diary of the transition in human culture" because he believes physics is arriving at another shifting point. His latest work Arrows of Time is a radical new form of cinema consisting of 40 interchangeable elements that deal with literature, philosophy, and contemporary physics. These elements are combined in a different order for each showing. This work premiered at the Museum of Modern Art in San Francisco in April 2007.
