Inspector Longhi: Age makes women grow to look more like each other. Don't you find that? Old men decay and each becomes quite distinct. Women seem to converge, eh?
Trivia: Despite repeated citations in print, (as recently as the 2001 edition of 'Film Facts' by Patrick Robertson), both Donald Sutherland and Julie Christie maintain that the sex scene between them was, in fact simulated, and they did not actually have sex, as has been widely reported.
