Taylor Russell and Timothée Chalamet make fine young cannibals in Luca Guadagnino’s audacious and astonishing ‘80s-set body horror romance Bones and All (B+). This walk on the wild side chronicles a twee twosome who feast on flesh, and there’s generally sufficient allegory to transcend the most gruesome episodes. Opposite the mesmerizing central couple who very comfortably occupy their pulpy roles, Mark Rylance is also absolutely unhinged as a terrifically terrifying man-eating mentor. Guadagnino guides his story gracefully into truly dark territory and finds sufficient humanity in his curious macabre. This offbeat road trip follows in the tradition of Bonnie and Clyde and Natural Born Killers and will not be for all tastes.
