Jacqueline Susann made publishing history as the first writer to have three consecutive number one novels on the "Times" list. The book was filmed in 1975 by Guy Green as "Jacqueline Susann's Once Is Not Enough", with Kirk Douglas, Alexis Smith, Melina Mercouri, Brenda Vaccaro (in an Oscar-nominated performance), and Deborah Raffin as January. The film, executive-produced by Irving Mansfield, was not a critical favorite, but was a commercial success, grossing $15.7 million (the equivalent of $65.2 million in 2016).) Susann's final work was a novella, "Dolores" (Morrow), a "roman a clef" about Jacqueline Kennedy, originally written for the February 1974 issue
