### Plot
Jill Young, as a child on her father's African farm, buys a baby gorilla from two natives, names him Joe, and raises him, lulling him to sleep with the song "Beautiful Dreamer" (words and music by [Stephen Foster](https://www.edgepedia.org/stephen-foster)).[1](https://catalog.afi.com/Film/26024-MIGHTY-JOE-YOUNG) Twelve years later, the fast-talking Hollywood impresario Max O'Hara travels to Africa to collect animals and publicity for his new exotic nightclub.[1](https://catalog.afi.com/Film/26024-MIGHTY-JOE-YOUNG) He encounters the gorilla, now about 12 feet (3.7 m) tall, and after failing to lasso it discovers it is Jill's pet; he persuades her to bring Joe to the United States, where the pair perform in a nightclub act in which Joe holds Jill above his head as she plays "Beautiful Dreamer" on a grand piano.[2](https://sf-encyclopedia.com/entry/mighty_joe_young) • [5](https://www.empireonline.com/movies/reviews/mighty-joe-young-review/)
Nightclub patrons feed Joe liquor and mistreat him, and the intoxicated gorilla goes on a rampage, destroying the club.[6](https://www.commonsensemedia.org/movie-reviews/mighty-joe-young-1949) Facing a judge's death sentence, Joe escapes, and while fleeing the police he stops at a burning orphanage and rescues the children trapped inside, redeeming himself.[6](https://www.commonsensemedia.org/movie-reviews/mighty-joe-young-1949) • [2](https://sf-encyclopedia.com/entry/mighty_joe_young) The picture ends with the words, "Goodbye from Joe Young."[1](https://catalog.afi.com/Film/26024-MIGHTY-JOE-YOUNG)
## Production
**Origins.** Producer-writer Merian C. Cooper and director Ernest B. Schoedsack had been struck by the affectionate way audiences, especially children, had responded to [King Kong](https://www.edgepedia.org/king-kong), a character they had intended as an object of horror. They decided to make a film with another super-sized gorilla, one with more humor and personality whom the audience could see as a hero.[3](https://www.tcm.com/articles/28070/mighty-joe-young-1949) The project waited until after World War II, because both Cooper and Schoedsack were heavily involved in the war effort.[3](https://www.tcm.com/articles/28070/mighty-joe-young-1949) Arko, Inc. was formed to make the picture by RKO and Argosy Pictures, the production company owned by the presenters [John Ford](https://www.edgepedia.org/john-ford) and Merian C. Cooper.[1](https://catalog.afi.com/Film/26024-MIGHTY-JOE-YOUNG) The working titles were *Mr. Joseph Young of Africa* and *The Great Joe Young*.[1](https://catalog.afi.com/Film/26024-MIGHTY-JOE-YOUNG) Live-action sequences were shot from mid-December 1947 to early March 1948.[1](https://catalog.afi.com/Film/26024-MIGHTY-JOE-YOUNG)
**Animation and effects.** Cooper brought back Willis O'Brien, the technical-effects expert on *King Kong*, to head the special-effects crew, and much of the animation work was done by [Ray Harryhausen](https://www.edgepedia.org/ray-harryhausen), who ended up performing over 80 percent of it.[4](https://archives.lib.byu.edu/repositories/14/archival_objects/363431) • [3](https://www.tcm.com/articles/28070/mighty-joe-young-1949) Harryhausen, who had been entranced by *King Kong* as a teenager, was hired after O'Brien saw rushes for his personal film *Evolution*.[3](https://www.tcm.com/articles/28070/mighty-joe-young-1949) Four models of the ape were used, built on ball-and-socket armatures of small machine parts, with foam-rubber muscles, fur, and interior wires controlling the face for full expression.[3](https://www.tcm.com/articles/28070/mighty-joe-young-1949) Lessons from *King Kong* improved puppet construction: new fur-application techniques greatly reduced the unintended movement of fur during handling, the so-called "boiling" effect.[7](https://propstoreauction.com/lot-details/index/catalog/525/lot/208920/242A-Original-15-Inch-Mighty-Joe-Young-Stop-Motion-Animation-Puppet-MIGHTY-JOE-YOUNG-1949?url=%2Fauctions%2Fcatalog%2Fid%2F525%3Fpage%3D10%26view%3Dgrid) Split-screen, traveling matte shots, and front and rear projection integrated the models with the live action.[3](https://www.tcm.com/articles/28070/mighty-joe-young-1949) The special-effects unit consumed most of the production's time and money.[4](https://archives.lib.byu.edu/repositories/14/archival_objects/363431)
**On set.** Schoedsack directed the film while legally blind, his sight having deteriorated to a blur during World War II; he relied on assistant director Sam Ruman to describe what was happening on set.[3](https://www.tcm.com/articles/28070/mighty-joe-young-1949) Although John Ford was credited as a co-producer, he left the production before principal photography began.[3](https://www.tcm.com/articles/28070/mighty-joe-young-1949) Ten professional wrestlers and boxers, including former heavyweight champion [Primo Carnera](https://www.edgepedia.org/primo-carnera), appeared in a nightclub tug-of-war scene with the gorilla.[1](https://catalog.afi.com/Film/26024-MIGHTY-JOE-YOUNG) • [3](https://www.tcm.com/articles/28070/mighty-joe-young-1949) RKO borrowed [Terry Moore](https://www.edgepedia.org/terry-moore-actress) from Columbia for the production.[1](https://catalog.afi.com/Film/26024-MIGHTY-JOE-YOUNG) A billboard advertising O'Hara's club, where "Mighty Joe Young" was appearing, gave the address 9336 Washington Boulevard, the address of the RKO studios where Argosy kept its offices.[4](https://archives.lib.byu.edu/repositories/14/archival_objects/363431)
## Reception and legacy
The film did only moderate business and failed to earn enough to cover its costs.[4](https://archives.lib.byu.edu/repositories/14/archival_objects/363431) Critics have generally treated it as a gentler companion to *King Kong*: the Science Fiction Encyclopedia calls it "a virtual remake, though on a smaller scale," while Empire describes it as "a 1949 for-kids version of the King Kong story still boasting a lot of charm," noting that the savagery and horror of the earlier film are absent and that Joe becomes destructive only when troublemakers get him drunk.[2](https://sf-encyclopedia.com/entry/mighty_joe_young) • [5](https://www.empireonline.com/movies/reviews/mighty-joe-young-review/) On the review aggregator Rotten Tomatoes the film holds a 91% Tomatometer from 22 reviews.[8](https://www.rottentomatoes.com/m/1013884-mighty_joe_young)
The film's lasting importance lies in its animation. It was the first major movie to benefit from Ray Harryhausen's stop-motion work, and O'Brien's supervision of the model animation won him, in the words of the Science Fiction Encyclopedia, "some belated recognition as well as an Academy Award" after years with few successes following *King Kong*.[3](https://www.tcm.com/articles/28070/mighty-joe-young-1949) • [2](https://sf-encyclopedia.com/entry/mighty_joe_young) Harryhausen went on to become a leading monster-animator of the next generation.[5](https://www.empireonline.com/movies/reviews/mighty-joe-young-review/) A surviving 15-inch stop-motion puppet from the film, with its original armature and skin intact, is described by auctioneers as the only fully intact puppet known to survive from the production.[7](https://propstoreauction.com/lot-details/index/catalog/525/lot/208920/242A-Original-15-Inch-Mighty-Joe-Young-Stop-Motion-Animation-Puppet-MIGHTY-JOE-YOUNG-1949?url=%2Fauctions%2Fcatalog%2Fid%2F525%3Fpage%3D10%26view%3Dgrid)
**The 1998 remake.** Disney released a color remake on December 25, 1998, directed by Ron Underwood and starring [Bill Paxton](https://www.edgepedia.org/bill-paxton) as zoologist Gregg O'Hara and [Charlize Theron](https://www.edgepedia.org/charlize-theron) as Jill, with the gorilla realized through animatronics, computer graphics, and 40-percent-scale suits created by [Rick Baker](https://www.edgepedia.org/rick-baker).[9](https://d23.com/a-to-z/mighty-joe-young-film/) The remake includes cameos by Terry Moore and Ray Harryhausen during a fundraising scene.[6](https://www.commonsensemedia.org/movie-reviews/mighty-joe-young-1949)
