A novel but remarkably un-gimmicky experiment in filmmaking occurs when we watch 'Dogme 95' co-founder Lars von Trier challenge his older mentor Jorgen Leth to remake Leth's 1968 short film, 'The Perfect Human.' The catch: Leth must remake the film five times, each time with a new set of rules (or "obstructions") from the tricky von Trier. Not to be outfoxed, the gifted Leth produces a series of beautiful, funny and personally revealing gems of cinema.
