Proof-of-concept trailers are often more about good editing than decent shots, often blending existing footage from other films with some hastily shot live-action scenes and some visual effects work.
Every now and then though one leaves a major impression, such as today's for "Enemy Of Man," an ambitious new film adaptation of Shakespeare's "Macbeth" that is currently seeking Kickstarter funds.
The trailer boasts an impressive cast including Sean Bean as the Scottish prince, Jason Flemyng as Macduff, Charles Dance as King Duncan, James D'Arcy as Banquo, Rupert Grint as Ross and Neil Maskell as Kern. Lady MacBeth they're keeping the identity of under wraps though Charlotte Gainsbourg's name has been linked.
According to the Kickstarter page for the film, the plan is to showcase a "unique cinematic quality, stripping back the dialogue and cranking up the action. It traverses a bleak, frozen landscape of shattered castles and pillaged towns, rendering the interior world that clouds Macbeth and Lady Macbeth’s addled minds, as they sink deeper into their heart of darkness."
