St. Elmo is a 1914 American silent drama film produced by the Balboa Amusement Producing Company and distributed by William Fox's Box Office Attractions Company. It was the first feature-length film adaptation of Augusta Jane Evans's 1866 novel of the same name. The story follows the life of the title character (played by William Jossey), who kills his cousin (Francis McDonald) over the love of Agnes (Madeline Pardee), falls from grace, and eventually finds redemption and love with Edna (Gypsy Abbott). It is disputed who directed the film; many sources credit Bertram Bracken, while others list St. Elmo as J. Gordon Edwards's directorial debut.

Plot

St. Elmo Murray and Murray Hammond, his cousin and best friend, are both in love with a young woman named Agnes Hunt. Although Agnes loves Murray, she rejects him for being too poor. Instead, she accepts the wealthy St. Elmo's marriage proposal. St. Elmo's mother holds a ball to celebrate the engagement. After the betrothal is publicly announced, Murray and Agnes meet covertly in the gardens. St. Elmo discovers their affair, challenges Murray to a duel, and kills his cousin with the first shot. The Devil possesses St. Elmo, and he becomes a cruel wanderer, spreading misery and misfortune where he travels.
