Plot

Dexter Riley, a science student at Medfield College, and his fellow students are developing a new vitamin compound when an accident in the laboratory produces a supercharged blend that finds its way into Dexter's cereal box. After breakfast the next morning, Dexter is transformed, with strength enough to level lampposts and destroy doorknobs.³ He wrongly credits his strength to a vitamin formula a classmate created, as two competing cereal makers battle to control the secret ingredient and sponsor a weight-lifting match pitting Medfield against its rival, State College.² Medfield is losing badly when Dexter realizes that his own compound, not the other student's, is the secret of his strength, and he leads his team to victory.²

The frame story gives Dean Higgins (Joe Flynn) a financial motive: Regent Dietz (Harold Gould) demands his resignation because the college is losing money, and Higgins begs for thirty days to raise school revenues.⁶ The strength formula becomes his plan to save the school, and he demonstrates its effects for the chairman of a cereal company (Eve Arden) and her board.⁷

Cast and production

Kurt Russell, a Disney contract player since childhood, played Dexter Riley in all three Medfield films; Walt Disney himself had signed him to an exclusive studio contract, and Russell made 12 Disney features in all.⁸ Joe Flynn, known for playing Captain Wallace Burton Binghamton on the television series McHale's Navy, played Dean Higgins; he died shortly after the film was completed in 1974, and this was his last feature film appearance.¹ Cesar Romero and Dick Bakalyan reprised their roles as the gangster A.J. Arno and his sidekick Cookie, who are offered an industrial espionage job on their release from prison.¹^•⁷ William Schallert reprised his role as Professor Quigley and Michael McGreevey as Schuyler from The Computer Wore Tennis Shoes.¹

Production details. Principal photography began on 28 May 1974 at the Walt Disney Studios in Burbank, California.¹ The main building of Medfield College, used across the series, was in fact the Animation Building on the Disney Studio lot, and location shooting took place in New Chinatown, Griffith Park, Echo Park, and a federal penitentiary, all in Los Angeles.² Robert F. Brunner, who scored all three Medfield films, wrote the music, including a running theme called "Instant Muscle" featuring jazz and Oriental themes along with two school marching band songs.¹^•² The crew included producer Bill Anderson, cinematographer Andrew Jackson, and editor Cotton Warburton.¹

Release and reception

The film opened in Los Angeles on 12 February 1975 and in New York on 9 July 1975, after the general United States release date of February 6, 1975.⁶^•³ A trade report in April 1975 projected a gross of $8 million, which would make it the most successful of the three Medfield comedies.¹ On the review aggregator JustWatch's linked ratings, the film holds an IMDb score of 5.9 from about 4,200 user ratings.⁵ A DVD release followed on May 4, 2004.⁹

The film remains in circulation as part of Disney's catalog: it streams on Disney+ in the United States and can be rented or purchased digitally on Amazon Video, Apple TV Store, Google Play, YouTube, and Fandango At Home.⁵^•⁹

Place in Disney's live-action comedies

The film belongs to a Disney tradition of campus-set live-action comedies that began with The Absent-Minded Professor in 1961, in which outlandish science-driven plots played out against all-American college backdrops.¹⁰ The Medfield trilogy followed this pattern, with Russell's Dexter Riley at the center of each film and recurring actors, composer, and screenwriter carrying over from entry to entry.¹ TCM's retrospective notes that Flynn, nominally the true star of the film, did not live to see its February 1975 release.¹⁰
