During the production of the screen adaptation of Leo Tolstoy's Anna Karenina (starring Greta Garbo, 1927), the film's producers decided to change the title because they feared that a foreign name would confuse American audiences. After considering various one-word titles, they settled upon "Heat." Screenwriter Frances Marion, however, promptly persuaded them to reconsider. "I think that would be a good ad for Dante's Inferno," she cried, "but I'd hate to see on the billboards: Greta Garbo in Heat!"
