Animation is used to show the beanstalk growing in Jack's backyard. Many television stations that aired the film normally transmitted black-and-white shows and movies with color equipment turned off, so they ran the sepia tone openings and closings in black and white while running the color portion in color. Like The Wizard of Oz, the film's opening and closing segments were presented in sepia tone – although many of the DVD releases present these sequences in black and white – while the entire "Jack and the Beanstalk" story was filmed in Eastmancolor and presented in the SuperCineColor process (Eastmancolor in subsequent releases). Jack and the Beanstalk was filmed from July 9 through Augat Hal Roach Studios on sets from Joan of Arc (1948). distributed both films but did not provide financing or production services. Utilizing a clause in their contract with Universal that allowed the team to make one independent film per year, Costello's company, Exclusive Productions, shot this film in 1951 and Abbott's company, Woodley Productions, made a second color film, Abbott and Costello Meet Captain Kidd in 1952. Since Universal-International would not spend the money to make an Abbott and Costello film in color, the duo decided to produce color films themselves. Mel Blanc provides the voices of the woodland animals of the Giant's land.

After greeting Eloise and Arthur as their storybook counterparts, Jack dances off into the night with the bravado of "Jack the Giant-Killer". Jack's cries out, but receives a second blow to the head from Dinkle, which returns Jack to his dream state. Just before being rewarded by the King for heroism, Jack is rudely awakened when Donald breaks a vase over Jack's head just as Eloise and Arthur return home from rehearsal. The villagers rejoice by dancing around the hole the Giant made from his fall. Once all reach the ground, Jack chops down the beanstalk, sending the Giant falling to his death. During the descent, Dinklepuss loses Nellie (who falls into the arms of Jack's mother) and then the gems, which rain down upon the impoverished townsfolk below. They flee down the beanstalk with the Giant in pursuit. They befriend his housekeeper, Polly, who helps them escape over the castle wall along with the royal prisoners, Nellie and some of the Giant's stolen gems (pilfered by the greedy Dinklepuss). The Giant releases Dinklepuss and Jack from the dungeon in order to toil around his castle. The princess falls for the troubador only to later learn this is the same prince she was betrothed. When they reach the top of the beanstalk Jack and Dinklepuss are captured by the Giant and imprisoned with the prince and princess. Upon learning of Nellie's existence, Dinklepuss joins Jack on the adventure. He decides to climb the beanstalk to rescue everyone from the Giant's clutches and retrieve "Nellie", the golden-egg laying hen that the Giant previously stole from Jack's family. Jack's mother, exasperated over the beans, tells Jack to plant them and a gigantic beanstalk grows overnight.

Upon returning home, Jack learns that the Giant has also kidnapped the princess and Henry. The unscrupulous Dinklepuss pays Jack five "magic" beans for the cow. Along the way Jack meets the prince, disguised as a troubador, who is kidnapped by the Giant soon afterward. His mother sends him to sell the last family possession, their beloved cow "Henry", to the local butcher, Mr. The dire situation obliges the kingdom's princess to marry a prince from a neighboring kingdom whom she has never met.


In his dream, Jack learns that a Giant, who lives in a castle in the sky, has taken all of the kingdom's food as well as the crown jewels. In his slumber, Jack dreams that he is the young Jack of the fairy tale. Bemused by Jack, Donald reads the story instead - a role-reversal made complete when Jack falls asleep as Donald reads. Polly sends Dinkle and Jack to babysit, but an attempt to lull the boy to sleep by reading the fairy tale Jack and the Beanstalk (Jack's "favorite novel") aloud fails when Jack stumbles over the larger words. Jack flirts with Cosman employee Polly, but he is thwarted by the arrival of her boyfriend, a towering police officer. Dinkle and Jack just happen to be seeking work. Eloise phones the Cosman Employment Agency, where Mr. Eloise Larkin and her fiancé Arthur's plans to attend the rehearsal of a play are jeopardized because no one will babysit her obnoxious kid brother Donald.
