A big, bright cast including Gig Young, Beatrice Arthur, Cloris Leachman and Diane Keaton (in her debut) can't quite make this lackluster comedy worth seeing. A critical success at the time, the film, about young lovers prepping their respective families for their upcoming wedding, is full of subplots that don't play, fall flat, or are gratingly unfunny. It begins promisingly but soon comes undone, and Cy Howard's direction is like that of a traffic cop. Arthur has the funniest moments as the all-knowing mother of the groom, and Keaton is very attractive. Oscar winner for its lovely theme song, "For All We Know". *1/2 from ****
