In Disney's live action The Jungle Book, King Louie, who was an orangutan in the 1967 animated film, is a Gigantopithecus, an ancient, giant ape, which some people think is an ancestor of Bigfoot (or Bigfoot is a Giagantopithecus.)
Another cool fact concerning The Jungle Book and cryptozoology: in British Columbia (and other places) before the terms "sasquatch" and "Bigfoot" were well known, hairy, man-like creatures were sometimes called "Mowglis," probably named after the feral boy in Rudyard Kipling's story.
ScienceNews.com has an interesting article on the subject of King Louie that starts like this:
"In the 1967 animated Disney film The Jungle Book, the feral boy Mowgli encounters a jazz-singing orangutan named King Louie, who implores Mowgli to teach him the secret of fire. King Louie presented a challenge for the producers of Disney's live-action, GCI-enhanced remake of the film, opening April 15. 'We had this notion that we would be as authentic as we could be to the region,' says producer Brigham Taylor. The problem: orangutans are not native to India.
"In fact, King Louie himself is not native to Rudyard Kipling's original stories. But instead of scrapping the character, the filmmakers got creative. While researching India's wildlife, the film's art department learned that a colossal ape named Gigantopithecus once roamed the region. Various species of Gigantopithecus lived in India, China, and Southeast Asia from about 6.5 million years ago to as recently as a few hundred thousand years ago. The ape was truly gigantic - by some estimates, twice as large as a gorilla."
