Ida Alexa Ross Wylie, known by her pen name I.A.R. Wylie, was an Australian-British-American novelist, screenwriter, short story writer, poet, and suffragette sympathiser who was honored by the journalistic and literary establishments of her time, and received international recognition for her works. Between 1915 and 1953, more than thirty of her novels and stories were adapted into films, including Keeper of the Flame (1942), which was directed by George Cukor and starred Spencer Tracy and Katharine Hepburn.

Keeper of the Flame is a 1942 American drama film directed by George Cukor, and starring Spencer Tracy and Katharine Hepburn, released by Metro-Goldwyn-Mayer (MGM). The screenplay by Donald Ogden Stewart is adapted from the 1942 novel Keeper of the Flame by I. A. R. Wylie. Hepburn plays the widow of a famous civic leader who has died in an accident. Tracy portrays a former war correspondent who intends to write a flattering biography of the dead man, only to find that his death is shrouded in mystery. Screenwriter Stewart considered the script the finest moment of his career, feeling vindicated by the assignment as he believed that Hollywood had punished him for years for his political views. Principal filming began in the last week of August 1942, four months after the release of the novel, published by Random House. The picture was filmed on a sound stage, with no location shooting. Hepburn had already begun a relationship with Tracy, and his heavy drinking led her to become his vigilant guardian during the filming.
