The national origin of Captain Nemo was changed in most movie realizations; in nearly all picture-based works following the book Nemo was made into a European. However, he was represented as an Indian by Omar Sharif in the 1973 European miniseries The Mysterious Island. Nemo is also depicted as Indian in a silent film version of the story released in 1916 and later in both the graphic novel and the movie The League of Extraordinary Gentlemen. In Walt Disney's 20,000 Leagues Under the Sea (1954), a live-action Technicolor film version of the novel, Captain Nemo is a European, bitter because his wife and son were tortured to death by those in power in the fictional prison camp of Rura Penthe, in an effort to get Nemo to reveal his scientific secrets. This is Nemo's motivation for sinking warships in the film. He is played in this version by the British actor James Mason, with an English accent. No mention is made of any Indians in the film.
