A sort of “Divorce Finnish Style,” Mika Kaurismäki's rambunctious new comedy, The House of Branching Love, recounts the breakup of a thirtysomething professional couple. Juhani is a family therapist, and his wife, Tuula, a successful business trainer. They're determined to keep things amicable until they sell their house, but when Juhani brings home a girl he picks up in a club, Tuula flips. The very next day, she brings home her own conquest in retaliation. Emotions long thought dead reappear, and the war escalates precipitously when Juhani begins searching for someone to make Tuula equally jealous.
