The most audacious Canadian feature in many a moon, Denis Cote’s fourth effort attains a rare state of Herzogian weirdness. Opening as a quasi-doc portrait of Jean-Paul Colmor, the affable proprietor of an enormous junkyard in the backwoods of Quebec, Carcasses then shifts into a more flagrantly mythic mode as Colmor’s metal-strewn kingdom is invaded by teen marauders. That the latter group is played by actors with Down’s syndrome may cause some consternation but the proceedings’ air of quiet awe and spirit of playfulness make Carcasses something rare and wondrous.
