I've repeatedly said that for people as little in common as Joanne and myself, we have an uncommonly good marriage. We are actors, we make pictures — and that's about all we have in common. Maybe that's enough. Wives shouldn't feel obligated to accompany their husbands to a ball game, husbands do look a bit silly attending morning coffee breaks with the neighbourhood wives when most men are out at work. Husbands and wives should have separate interests, cultivate different sets of friends — and not impose one upon the other.
