(CNN) -- Maybe marriage to Kate Winslet isn't all that bad. Maya Rudolph and John Krasinski star as a couple on the road in the comedy "Away We Go." After cruelly dissecting marital malaise in "American Beauty" and again, just six months ago, in "Revolutionary Road," Winslet's husband Sam Mendes takes a slightly more optimistic view of family life in the edgy comedy "Away We Go." Not that he's offering a whole-hearted endorsement of the institution. Burt and Verona (John Krasinski and Maya Rudolph) aren't legally bound -- she staunchly resists his repeated proposals -- but nevertheless they're a couple about to go nuclear: She's six months pregnant.
