Numbed by career demands and a recent divorce, Dr. Alexandra Kendall hides behind a hard shell of professional detachment. Then she treats Buffy Koenig, a dying 17-year-old cancer patient who reawakens Kendall to life's possibilities. Eventually, Buffy's deteriorating condition forces Dr. Kendall to weigh the consequences of keeping a promise that she had made.
Writer Loring Mandel conceived the story for Promises in the Dark while he was employed as head writer for the daytime drama Love of Life. When the soap's executive producer Darryl Hickman rejected the idea, Mandel quit the show and developed the plot into a feature screenplay.
The project was initially in development at United Artists, with Elizabeth Ashley cast in the starring role, John Schlesinger set to direct and Arnold Schulman and Jerome Hellman producing. However, with the exception of Hellman, no one remained with the project, which was inactive for many years. Arthur Krim, chairman of the newly formed Orion Pictures, selected the script as one of the company’s first projects on the strength of Hellman’s previous productions, such as Midnight Cowboy and Coming Home. In addition to serving as producer, Hellman directed the film.[5]
Promises in the Dark was filmed partly on location at Manchester Memorial Hospital in Manchester, CT.[6]
