    • The dolphins who appeared in this film were trained by Peter Moss, Kathy Trout and Erica Abt.

  • Quotes

    • Dr. Jake Terrell: [on returning to the island]: I go away for one lousy afternoon and the whole place falls apart!

    • Dr. Jake Terrell: [discussing dolphins]: Why, as mammals, were they compelled - or did they decide - to leave the land and return to the sea?

    • Harold de Milo: Are you a blackmailer, Mr. Mahoney?
      Curtis Mahoney: Goodness, no! I'm just an average guy with an above-average curiosity.

  • Notes

    • Robert Merle's novel was originally called Un Animal Doue De Raison (An Animal Endowed With Reason) and was originally published in French in 1967. It was an international best-seller, appearing in English translation in 1969, but making a film of it proved very difficult. Roman Polanski was working on it with the writer James Salter at the time of his wife's murder; he then dropped the project.

    • This film, like Robert Merle's original novel, was inspired by the researches of Dr. John Lilley. He threatened the makers of the film with a lawsuit, although it came to nothing (perhaps because the film was a box-office flop).
