Hearts Adrift is a 1914 silent short romance film directed by Edwin S. Porter. The film is now considered lost.
The film bears a great resemblance to the 1911 story As the Sparks Fly Upward by Cyrus Townsend Brady. The film didn't credit Brady, who sued the studio. The film's story also bears resemblance to the 1908 novel The Blue Lagoon by Henry De Vere Stacpoole, which was filmed in 1923 and several decades later with Jean Simmons in 1948 and Brooke Shields in 1980.
The film proved to be a huge success. Actress Mary Pickford eventually demanded a higher salary as her popularity rose because of this film.
Nina (Mary Pickford) and Jack Graham (Harold Lockwood) are both marooned on a deserted island. They fall in love and eventually Nina gives birth to a child. Despite being stranded, they are very happy together. One day, Jack's wife comes to rescue him. Nina is crushed and throws herself in a volcano.
