Mighty Joe Young is a 1949 American giant monster film produced by Argosy Pictures and distributed by RKO Radio Pictures. The movie was released to American theaters on July 27, 1949.


in 1937 Africa, Jill Young is living with her father on his ranch. While in her yard, two Africans come by with an orphaned baby gorilla; Jill so wants a pet that she trades her toys and money for him, vowing to always care for the gorilla.

Twelve years later, Max O'Hara and sidekick Gregg are on a trip to Africa looking for animals to headline in O'Hara's new Hollywood nightclub. The two men have captured several lions and are about to leave when gorilla Joe Young appears, now 12 feet (3.7 m) tall and weighing 2,000 pounds (910 kg). When a caged lion bites Joe's fingers, he goes on a rampage. Visualizing Joe as their big nightclub attraction, Max and Gregg try to rope him, but he throws both men from their horses and breaks free of their ropes. A grown Jill Young arrives, calming Joe down. She is furious with both men and storms off with Joe.

Both later meet with Jill, and Gregg becomes hopelessly smitten with her. Having now calmed down, Jill hears out Max's nightclub proposal, as Gregg also tries to dissuade her. Max tells her that she and Joe will be a huge Hollywood hit and will be rich within weeks. Needing the proffered income, she agrees to take Joe to Hollywood.

On the crowded opening night, on stage Joe lifts a large platform above his head, holding Jill playing Beautiful Dreamer on a grand piano. Following that, Joe has a tug of war with "the 10 strongest men in the world", which he easily wins. Famous Italian heavyweight boxer Primo Carnera tries to box with him, but Joe playfully tosses him into the audience; laughter follows.

Joe's popularity grows, and by the 10th week he is Hollywood's biggest nightclub attraction. Joe and Jill, however, are beginning to miss Africa; Jill tells Max and Gregg that she is having second thoughts. Gregg tries to convince Max to let them go, but thinking only about more profit, he is able to talk her into staying.

By the 17th week, Joe is miserable; he has grown tired of performing and is homesick. To make matters worse, his next act is a humiliating performance playing an organ grinder with Jill, acting as a little girl, turning the handle. When a thrown bottle strikes Joe, his rage surfaces, roaring at the crowd, while Jill shouts for the audience to stop. Later, during dinner, Gregg and Jill express their feelings for one another, with Gregg agreeing to return with her to Africa.

In his cage, an unhappy Joe tries to ignore three drunks who have sneaked backstage; they offer Joe an open whiskey bottle, and he becomes intoxicated after two more open bottles are consumed. Taunting him, the drunks burn Joe's fingers with a cigarette lighter. Roaring with pain and rage, he breaks out, smashing through a nearby wall and wrecking the nightclub's interior. He also smashes the glass of the lion habitat, allowing the lions to escape into the crowded nightclub, where Joe beats down several of them. Jill and Gregg return and find the nightclub in chaos. Jill manages to get Joe back to his cage, while arriving police shoot the remaining lions.

A court decree orders Joe be shot, and Jill's pleas to save his life are denied. Gregg, O'Hara, and Jill devise a plan to get Joe out of California using a moving van, then a cargo ship. When Joe's executioners arrive, they find his cage empty and themselves locked inside the nightclub. As the van is leaving, Joe is spotted by an itinerant worker, who is later questioned by police. On the way to the ship, police spot the moving van and give chase, but Joe has been cleverly transferred to a covered truck; the moving van, driven by Max, is just a decoy. The police eventually stop the van and arrest Max.

Driven by Gregg and carrying Joe and Jill, the truck gets stuck in heavy mud. With Jill's encouragement, Joe pushes the truck free, and the police then get stuck in the same mud as the truck drives away. Before reaching port, they witness a tall orphanage engulfed in flames.

Jill and Gregg help the caretakers save the children. They escort most of the children, but the flames spread quickly, and a last group, along with Jill and Gregg, are trapped on the top story. At Jill's urging, Joe braves the raging fire by climbing an adjacent tall tree, carrying Jill to safety, while Gregg lowers each child by rope to the ground. One child is left behind, so Joe climbs up again, grabbing the little girl, then he and Gregg climb down. A wall of the burning orphanage collapses as they near the ground, nearly killing Joe and the little girl. Max assures Jill that, because of Joe's heroism, his life will now be spared.

Much later, Max receives home movies from his friends. Jill and Gregg, now married and living on their ranch with Joe, who has made it safely back to Africa. Joe waves "goodbye", along with Jill and Gregg, to Max.

Willis O'Brien, who created the animation for King Kong, was the supervisor of the film's stop-motion animation special effects. Ray Harryhausen was hired in 1947 on his first film assignment as an assistant animator to O'Brien. O'Brien, however, ended up concentrating on solving the various technical problems of the production, delegating most of the actual animation to Harryhausen; Pete Peterson and Marcel Delgado also animated a few sequences in the film.

The models (constructed by Kong's builder Marcel Delgado) and animation are more sophisticated than in King Kong, containing more subtle gestures and even some comedic elements, such as a chase scene where Joe is riding in the back of a speeding truck and spits at his pursuers. Despite this increased technical sophistication, this film, like King Kong, features some serious scale issues, with Joe noticeably changing size between many shots (the title character is not supposed to be as large as Kong, perhaps 10–12 feet tall). Harryhausen attributed these lapses to producer Cooper, who insisted Joe appear larger in some scenes for dramatic effect.

Buoyed by the enormous success of King Kong in 1933 and its profitable theatrical reissues in 1938, 1942, and 1946, RKO had great hopes for Mighty Joe Young. Upon its release in 1949, the film was honored with an Academy Award for Special Effects (a category that did not exist in 1933 for King Kong).

The film has become a stop-motion animation classic. Special effects artists consider it highly influential, with the elaborate orphanage rescue sequence lauded as one of the great stop-motion sequences in film history. It was remade in 1998 with Charlize Theron playing Jill, Bill Paxton as Greg, and creature suit performer John Alexander as the title character. Joe was created through a mixture of gorilla suits and full-sized animatronics created by Rick Baker and digital effects by DreamQuest Images and Industrial Light & Magic.

Unmade sequel

The film was unsuccessful at the box office and recorded a loss of $675,000. As a result, plans to produce a sequel Joe Meets Tarzan were quickly dropped.
