Experimental Danish director Lars von Trier has revealed his latest film concept - Lookey.
Lars Von Trier won the Palme D'or at Cannes in 2000
The man behind films such as Dogville and The Idiots has included deliberate, out-of-context things in his latest film The Boss of It.
It is these things, Von Trier explained, that are "Lookey".
"For the casual observer it's just a glitch or mistake but for the initiated it's a riddle to be solved," he told industry website Screen Daily.
Von Trier shot the comedy using his conceptual Automavision technique, which involves allowing a computer to choose when to tilt, pan or zoom from a fixed camera position.
He described Lookey as a "basic mind game, played with movies as game boards."
The idea is for the viewer to identify all the Lookeys in the film - said to be between five and seven - with a prize of 30,000 Danish kroner (£2,728) going to the first person to do so.
Von Trier, 50, is renowed for exploring new film concepts.
He was behind the Dogme95 collective, who called for a return to simple film-making.
Under the rules, a Dogme film could not use props or sets, fixed cameras, special effects and could not conform to any existing film genre.
Von Trier's 1998 film The Idiots conformed to the rules, but he has gradully moved away from the concept.
In 2000, von Trier won the Palme d'Or at Cannes for his musical film Dancer in the Dark, starring Icelandic musician Bjork.
He completed Manderlay in 2005 - the second film in his USA trilogy. The first, Dogville, starred Nicole Kidman.
