If Harry is Reiner's alter ego, Sally is another Ephron heroine who gets "Heartburn," but how much more easily she finds the Maalox this time.
If that doesn't sound quite like the Ephron of old (certainly not the Ephron of "Heartburn," which had an undertaste so nasty you could be puckered for a month afterward), it's possibly because Reiner and Billy Crystal, longtime collaborators, reportedly added a good deal themselves during the film making.
The movie was written by Nora Ephron , and could be a prequel to her novel and screenplay " Heartburn ," which starred Jack Nicholson and Meryl Streep in the story of a marriage and divorce.
