Jacqueline Susann spent a long career on the edges of show business as an actress and model, but it never really paid off until she quit acting to write her first novel. Valley of the Dolls was a proudly sleazy potboiler that sold 26 million copies and had readers wondering which characters matched up to which real-life show-biz figures. Susann wrote several other successful novels, but fame and fortune didn't make her life any less tumultuous; she had well-publicized problems with drugs and alcohol and a series of free-wheeling affairs, although she stayed with her husband Irving Mansfield until her death in 1974 at the age of 56. Isn't She Great is a screen biography that focuses on Susann's roller-coaster literary career, with Bette Midler as Susann and Nathan Lane as Mansfield; David Hyde Pierce, Stockard Channing, John Cleese, and Sarah Jessica Parker round out the supporting cast.
