Exhausted by the challenge of filming Richard Yates’s tragic novel Revolutionary Road, Sam Mendes leapt at the chance to direct this funky, low-key comedy from a script by cult writer Dave Eggers (A Heartbreaking Work of Staggering Genius) and his wife, Vendela Vida. Yet the two movies aren’t as antithetical as they might seem: both center on iconoclastic young couples who hope a big move to a new locale will be the key to their future happiness. Maya Rudolph and John Krasinski star as longtime partners expecting their first child; when his parents announce that they’re leaving town, the couple decide to find a new home and set off on a cross-country trip to reconnect with family and old friends and check out possible places to live (Phoenix, Tucson, Madison, Montreal, Miami). The episodic structure works to the movie’s benefit, highlighting the eccentric supporting characters and allowing Mendes to smoothly downshift from hilarity to sadness. With Alison Janney, Jim Gaffigan, Maggie Gyllenhaal, Chris Messina, and Paul Schneider. R, 98 min.
