Anti-Clock is a 1979 film, an analytic drama in which dreams are imaged in computerized video, written and directed by Jane Arden, and co-directed by Jack Bond. The film, which stars Arden's son Sebastian Saville, was shot on film and video in colour with black and white sequences. It opened the 1979 London Film Festival, but was never picked up for British distribution: its only other public British screening was at the National Film Theatre in 1983 as a tribute to Jane Arden, who committed suicide at the end of the previous year. However, it had a modest theatrical release in the US, where it received considerable critical acclaim. Famed scientist Richard Feynman appears in the form of stock footage from his Messenger lectures on "The Character of Physical Law", and is credited as "The Physicist".
