From Tarzan, Lord of the Jungle:
The Ape Man (Robert Ridgely) discovers a tribe of Vikings, descended from a tribe that had landed in Africa more than 1,000 years earlier. Everything else is, well, predictable......
Lord of the Jungle has been described as the most faithful adaptation of the Edgar Rice Burroughs books, topping not only the movie series, but also Ron Ely's 1966-8 live-action series. Disney's subsequent adaptation, while it went far off the track, also enabled Tarzan to be well spoken.
