After interviewing celebrities (mostly) for the San Francisco Chronicle for the past 50 years, Ruthe Stein has written a memoir of her experiences — “Sitting Down with the Stars: Interviews with 100 Hollywood Legends.” Stein sits down with Total SF host Peter Hartlaub to talk about why she asks the uncomfortable questions, who are the nicest and most difficult stars and how she developed her own interest in Hollywood gossip. Hartlaub also asks Stein (his former editor) one tough question from the book: to defend her take that Jerry Lewis was kind of hot. “Sitting Down with the Stars” is available on Grizzly Peak Press.
