Random Harvest is a novel written by James Hilton, first published in 1941. Like previous Hilton works, including Lost Horizon and Goodbye, Mr. Chips, the novel was immensely popular, placing second on Publishers Weekly list of best-selling novels for the year, and it was published as an Armed Services Edition during WWII.

Random Harvest is a 1942 American romantic drama film based on the 1941 James Hilton novel of the same title, directed by Mervyn LeRoy. Claudine West, George Froeschel, and Arthur Wimperis adapted the novel for the screen, and received an Academy Award nomination. The novel keeps the true identity of Paula/Margaret a secret until the very end, something that would have been impossible in a film, where characters’ faces must be seen. This meant that the movie had to take a very different approach to the story. The film stars Ronald Colman as a shellshocked, amnesiac World War I veteran, and Greer Garson as his love interest.
