Question: Which Walt Disney production was based on Jules Verne's 1868 novel "Captain Grant's Children," The Misadventures of Merlin Jones or In Search of the Castaways?

Context paragraphs:
In Search of the Castaways: In Search of the Castaways (French: "Les Enfants du capitaine Grant" , lit.  "The Children of Captain Grant") is a novel by the French writer Jules Verne, published in 1867–1868.  The original edition, published by Hetzel, contains a number of illustrations by Édouard Riou.  In 1876 it was republished by George Routledge & Sons as a three volume set titled "A Voyage Round The World".  The three volumes were subtitled "South America", "Australia", and "New Zealand".  (As often with Verne, English translations have appeared under different names; another edition has the overall title "Captain Grant's Children" and has two volumes subtitled "The Mysterious Document" and "Among the Cannibals".)

Tom Ayrton: Tom Ayrton is a fictional character who appears in two novels by French author Jules Verne.  He is first introduced as a major character in the novel "In Search of the Castaways" (1867–1868).  He then reappears in a later novel, "The Mysterious Island" (1874), in which his fate, left unknown at the ending of the previous novel, is resolved, and during the course of which his character undergoes change and achieves a redemption.

The Mysterious Island: The Mysterious Island (French: "L'Île mystérieuse" ) is a novel by Jules Verne, published in 1874.  The original edition, published by Hetzel, contains a number of illustrations by Jules Férat.  The novel is a crossover sequel to Verne's famous "Twenty Thousand Leagues Under the Sea" and "In Search of the Castaways", though its themes are vastly different from those books.  An early draft of the novel, initially rejected by Verne's publisher and wholly reconceived before publication, was titled "Shipwrecked Family: Marooned With Uncle Robinson," seen as indicating the influence on the novel of "Robinson Crusoe" and "The Swiss Family Robinson".  Verne developed a similar theme in his later novel, "Godfrey Morgan" (French: "L'École des Robinsons", 1882).

The Children of Captain Grant (film): The Children of Captain Grant Russian: Дети капитана Гранта , "Deti kapitana Granta " is a 1936 Soviet adventure film directed by Vladimir Vaynshtok and David Gutman and starring Nikolai Cherkasov, Ivan Chuvelyov and Yuri Yuryev.  It is an adaptation of the novel "In Search of the Castaways" by Jules Verne.  The film was popular on its release, and was followed in 1941 by another Verne adaptation "Mysterious Island".  In the 1860s, two Scottish children go on a global search for their missing father, the sailor Captain Grant.

The Misadventures of Merlin Jones: The Misadventures of Merlin Jones is a 1964 Walt Disney production starring Tommy Kirk and Annette Funicello.  Kirk plays a college student who experiments with mind-reading and hypnotism, leading to run-ins with a local judge.  Funicello plays his girlfriend (and sings the film's title song written by brothers Robert and Richard Sherman).

The Monkey's Uncle: The Monkey's Uncle is a 1965 Walt Disney production starring Tommy Kirk as genius college student Merlin Jones and Annette Funicello (Who was a member of the mouseketeers from The Mickey Mouse Club) as his girlfriend, Jennifer.  The title plays on the idiom "monkey's uncle" and refers to a chimpanzee named Stanley, Merlin's legal "nephew" (a legal arrangement resulting from an experiment to raise Stanley as a human); Stanley otherwise has little relevance to the plot.  Jones invents a man-powered airplane and a sleep-learning system.  The film is a sequel to the 1964 film "The Misadventures of Merlin Jones."

The Castaways of the Flag: The Castaways of the Flag (French: "Seconde patrie" , lit.  "Second Fatherland", 1900) is an adventure novel written by Jules Verne.  The two volumes of the novel were initially published in English translation as two separate volumes: "Their Island Home" and "The Castaways of the Flag".  Later reprints were published as "The Castaways of the Flag".

In Search of the Castaways (film): In Search of the Castaways is a 1962 Walt Disney Productions feature film starring Hayley Mills and Maurice Chevalier in a tale about a worldwide search for a shipwrecked sea captain.  The film was directed by Robert Stevenson from a screenplay by Lowell S. Hawley based upon Jules Verne's 1868 adventure novel "Captain Grant's Children".  The film was Mills' third of six for the Disney Studios.

Mysterious Island (1961 film): Mysterious Island (UK: Jules Verne's Mysterious Island) is a 1961 science fiction adventure film about civil war prisoners who escape in a balloon and then find themselves stranded on a remote island populated by giant mutated animals.  Based very loosely upon the 1874 novel "The Mysterious Island" ("L'Île mystérieuse") by Jules Verne (which was the sequel to two other novels by Verne, 1867's "In Search of the Castaways" and 1870's "Twenty Thousand Leagues Under the Sea"), the film was produced by Charles H. Schneer and directed by Cy Endfield.  Shot in Spain and at Shepperton Studios, Shepperton, England, the film serves as a showcase for Ray Harryhausen's stop-motion animation effects.  Like several of Harryhausen's classic productions, the musical score was composed by Bernard Herrmann.

In Search for Captain Grant: In Search for Captain Grant (Russian: В поисках капитана Гранта , "V poiskakh kapitana Granta " , Bulgarian: По следите на капитан Грант ) is a 1986 Soviet 7-part television miniseries adaptation of Jules Verne's novel "In Search of the Castaways" directed by Stanislav Govorukhin.  It was shot on the Odessa Film Studio and Bulgarian Boyana Film in 1985.
