Judy Garland dismissal from the film, author Jacqueline Susann said in the 1967 television documentary 'Jacqueline Susann and the Valley of the Dolls', 'I think Judy will always come back. She kids about making a lot of comebacks, but I think Judy has a kind of a thing where she has to get to the bottom of the rope and things have to get very, very rough for her. Then with an amazing inner strength that only comes of a certain genius, she comes back bigger than ever'. Returning to the stage, Garland made her last appearances at New York's Palace Theatre
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
