Answer:
The first film adaptation of the tale, Frankenstein, was made by Edison Studios in 1910, written and directed by J. Searle Dawley, with Augustus Phillips as Frankenstein, Mary Fuerte as Elizabeth, and Charles Ogle as the Monster. The brief (16 min.) story has Frankenstein chemically create his creature in a vat. The monster haunts the scientist until Frankenstein's wedding night, when true love causes the creature to vanish. For many years, this film was believed lost. A collector announced in 1980 that he had acquired a print in the 1950s and had been unaware of its rarity.
The Edison version was followed soon after by another adaptation entitled Life Without Soul (1915), directed by Joseph W. Smiley, starring William A. Cohill as Dr. William Frawley, a modern-day Frankenstein who creates a soulless man, played to much critical praise by Percy Standing, who wore little make-up in the role. The film was shot at various locations around the United States, and reputedly featured much spectacle. In the end, it turns out that a young man has dreamed the events of the film after falling asleep reading Mary Shelley's novel. This film is now considered lost film.
