Although there’s nary a line as memorable as Gran Torino’s “Get off my lawn!” this time around, Clint Eastwood’s The Mule (B+) continues the actor/auteur’s loving curmudgeonly entreaty to the next generation to be kind to people even when the words coming from your mouth fail to express it, to take time for those you love even if you weren’t always great at this gesture in the past, to seek inner peace inside your family over the clarion calls of the outside world and to quit living on your damn cellphone. Eastwood as both director and leading man imparts his brilliant life lessons through an unconventional, deliberately paced tale and brings out lived-in performances from cast mates ranging from Bradley Cooper and Michael Peña as federal agents, Andy Garcia and Ignacio Serricchio as drug-lords and Dianne Wiest as the protagonist’s estranged ex-wife. The plot answers the question about what second career an old-school gardener can take in the internet age, and it’s not greeter at the local discount superstore. Eastwood’s enlistment as an inauspicious 90-year-old drug courier for a ruthless Mexican cartel provides the spry senior with a new job involving seeing the countryside, singing along to favorite radio oldies and procuring ample envelopes of cash, before the runs get increasingly dangerous. Many of Eastwood’s late-career (or is this mid-career?) films contemplate Big Issues, and he and screenwriter Nick Shenk (the man behind the words of Torino as well) do a splendid job balancing tangible tension and action, a marvelously relatable flawed hero and a small dusting of issues related to crime, class and race to be sorted out at your own leisure. Some mild quibbles include the hero’s occasional muttering of self-conscious soliloquy under his breath, inconsistencies about his spectrum of naiveté, some tender moments that get a little too treacly and pacing that could be a good bit tighter. But overall Eastwood’s metaphors are in full bloom, and he’s no passive rider in chronicling the American story. He’s still a major voice making movies that matter.
