Seven Footprints to Satan is a Synchronized sound 1929 American mystery film directed by Danish filmmaker Benjamin Christensen. Based on the 1928 story of the same name by Abraham Merritt, it stars Thelma Todd, Creighton Hale, William V. Mong and Sheldon Lewis. Although originally planned as a part-talkie, the film was released as a synchronized film only as evidenced by all period reviews that specifically mention that the film is "Synchronized" with Exhibitors Herald World specifically stating "there is no dialogue." The film features a synchronized musical score and sound effects along with English intertitles. The film survives at the Cineteca Italiana in an alternate sound version known as an International Sound Version. The sound disks for this foreign sound version are apparently not extant.
