Son of Flubber (1963) is a direct sequel to The Absent-Minded Professor (1961), the very successful gimmick comedy from Walt Disney Productions. The movie picks up precisely where The Absent-Minded Professor leaves off, as Prof. Ned Brainard (Fred MacMurray) again flies his flubberized flivver over Washington, D.C. He and passenger Biff Hawk (Tommy Kirk) avoid ducks as they fly to the Pentagon and meet with military brass about the promised compensation for the government's exclusive rights to Flubber (i.e. flying rubber, the weird bouncing substance that fueled the comedy of the first film). Unfortunately, red tape, bureaucracy, and a golf date means that Brainard has to return to cash-strapped Medfield College empty-handed. The Brainard household is also in dire financial straits – new wife Betsy (Nancy Olson) can't scrape fifty cents together to pay the paperboy. A team of corporate speculators has descended on the house with a check for a million dollars and an endless number of commercial uses for Flubber, but Brainard has to break it to them that the U.S. government is sitting on the rights. The good professor is not very worried, however; he has hit upon a new invention – flubbergas – with which he hopes to control the weather itself! When he takes aim at a cloud with a long-range flubbergas gun, however, he only succeeds in breaking everything made of glass within firing range. Local tycoon Alonzo P. Hawk (Keenan Wynn) still threatens to bulldoze Medfield College, but he makes a modest financial proposal to Brainard when he discovers the professor's latest invention. Hawk's son Biff, meanwhile, is more interested in using flubbergas to help the hapless Medfield football team win an upcoming game.

Son of Flubber proved to be an even bigger box-office success for Disney Pictures than The Absent-Minded Professor had been. Its reliance on silly slapstick effects and broad humor for kids set the tone for live-action comedies at Disney for at least the next decade. Director Robert Stevenson was still at the beginning of his second career as an exclusive Disney-only filmmaker. Following such prestigious properties as Joan of Paris (1942) and Jane Eyre (1944), Stevenson directed in television in the mid-1950s, then reinvented himself beginning with Disney's Johnny Tremain (1957). He directed twenty features in almost twenty years for Walt Disney; his films were consistent moneymakers such as Darby O'Gill and the Little People (1959), Mary Poppins (1964), That Darn Cat! (1965), and The Gnome-Mobile (1967), and by the mid-1970s he was acknowledged (sometimes with some level of derision) as "the most successful director of all time."

Son of Flubber is a delight for those interested in spotting familiar character comedians in minor roles. Several actors return from The Absent-Minded Professor, including Edward Andrews as Defense Secretary and Leon Ames as the President. Ed Wynn also returns, this time in a meatier role as a defense witness in the concluding trial. Joining the cast are Charlie Ruggles as the judge at the trial, and Jack Albertson and William Demarest as neighbors of Prof. Brainard. (Two years after this film Demarest would join the cast of MacMurray's long-running TV series My Three Sons). The long special-effects-laden football game sequence in the movie is enlivened by the ripe delivery of the game announcer, played by Paul Lynde in his feature film debut. Finally, the clever and satiric film-within-a-film which touts the many possible commercial applications of Flubber is hosted by the acerbic comic actor Joe Flynn. Flynn would go on to become something of a fixture in live-action Disney features, appearing in The Love Bug (1968), The Computer Wore Tennis Shoes (1969), The Barefoot Executive and The Million Dollar Duck (both 1971), among others. He would also provide a voice for their animated film The Rescuers (1977).

Bosley Crowther in The New York Times called Son of Flubber a "studious repeat, or rebound, of a good entertainment formula...It is crazy, of course, in the spirit of old-fashioned sight-gag slapstick farce, but it is fun – and, indeed, a bit of a satire on the weird inventions of the new atomic age. It has all the wholesome ingredients of perennial family comedy, including Mr. Disney's infant grandson in a small but expandable role." Time magazine called the film "insuperably sappy" but had praise for the broad humor, saying it would appeal to "...any moviegoer who needs a good, old-fashioned locomotive laugh. It's a flubbergasser."
