It is something of a relief to find Away We Go nestled in theaters among the summer season blockbustery craziness. It’s one of those rare movies that manages to be both wickedly funny and also incredibly poignant to the point where, yes, tears might be shed. Written by novelists and real-life married couple Dave Eggers and Vendela Vida and directed by Sam Mendes, the film revolves around a happily unwed couple (finally!), played by The Office’s John Krasinski and SNL alum Maya Rudolph, who are expecting their first baby and can’t figure out a place to put down roots. They’re in their mid-30s, essentially grown-up, but can’t shake the feeling that they are still somehow essentially screw-ups (raise your hand if this feels familiar). The road trip they set off on includes visits to family and friends, and terrific supporting performances by Alison Janney, Maggie Gyllenhaal, Catherine O’Hara, Jeff Daniels and Josh Hamilton. (Ms. Gyllenhaal might have studied some smug Park Slope mommies for inspiration for her character.) What could have easily derailed into precious twee-dom doesn’t. Get ready to be surprised by Maya Rudolph’s quietly powerful performance.
