Viggo Mortensen and Mahershala Ali are masterful in this rousing period piece, alternating belly laughs with an unflinching view of a nation at war with itself. Green Book charts a road trip into racism shared by two well-worn stereotypes, characters that, almost surprisingly, come from real life – ‘Tony Lip’ Vallelonga (a pizza-chomping Viggo Mortensen) is a brutal, racist NYC club bouncer prone to howyadoins. On the hunt for work, he gets an unlikely gig at the invitation of Don Shirley (cryptic Mahershala Ali, superb), a finicky black jazz pianist who requires a tough driver to escort him on a tour of the Deep South. Tony’s no bleeding heart, but for the right price, he’s willing to swallow his pride. Green Book may well move you, possibly to tears, at the thought of real social change and kindness (at a time when we need it badly).
