Every family has its stories, and every family has its drama — and some families, like the one the actor and director Griffin Dunne was born into, have an excess of both. His uncle was the writer John Gregory Dunne, his aunt was Joan Didion and his father was Dominick Dunne, who became famous for his Vanity Fair dispatches from the trial of the man who killed his daughter (and Griffin’s sister) Dominique.On this week’s episode of the Book Review podcast, Dunne talks about his book, “The Friday Afternoon Club: A Family Memoir.” Of waiting to write it until his father, uncle and aunt had died, Dunne said he needed the distance: “I had the perspective on just how remarkable those three were as writers, what an influence they had on my life.”
