Shadow of a Doubt was released on 12 January 1943.
Loosely based on Earle Nelson (considered “the first serial murderer in American history whose crimes were subject to widespread media attention”) who had been executed in 1928 for 22 murders, the script was written by Sally Benson, Alma Reville (Alfred Hitchcock’s wife), and Thorton Wilder.
Shadow of a Doubt was an immediate success and it’s status has improved over time; it is described as Alfred Hitchcock’s “first indisputable masterpiece.” Hitchcock himself often cited it as his favorite of his own films.
Thorton Wilder was nominated for an Academy Award for Best Original Motion Picture Story (although Gordon McDonell - husband of Margaret McDonell, head of David O. Selznick’s story department - is now cited as developing the idea).
