Jude Law stars an inventive short film being launched in the UK.

Starting Monday, UK cinemas will screen the short film directed by Jason Martin on behalf of Polish artist Pavel Althamer.

It will show during trailer presentations, subverting the notion of trailers because the film it promotes doesn't exist.

Instead, the short promotes an event at London 's Borough Market, Real Time Movie, which will kick off at 11:30 on Nov 30 and get the public involved in the street scene with actors including Law.

The short was commissioned by the Tate Modern as part of The World As A Stage and is being shown at Curzon cinemas, the Renoir and Vue. The short can also be found on YouTube.
