We’ll forgive you for assuming that Friends With Kids is a pseudo-sequel to Bridesmaids. Four alumni from last summer’s zeitgeist-destroying smash appear in writer and first-time director Jennifer Westfeldt’s heartfelt story about phase two of marital promise—parenthood. Chris O’Dowd and Maya Rudolph play a couple who notice the romantic sparks fading as their parental duties increase, and Kristen Wiig turns up in the surprisingly somber role of a woman whose marriage to the moody Jon Hamm isn’t all it’s cracked up to be. But Westfeldt, who is best known for starring in and co-writing the indie sleeper Kissing Jessica Stein—and for dating Mr. Hamm—wasn’t trying to capitalize on Bridesmaids’ runaway success. She was just trying to make the grueling process of moviemaking a touch easier by casting her unusually talented friends.
