The Strongest Man in the World is a 1975 comedy film released by Walt Disney Productions, and the third and final film in the Dexter Riley trilogy starring Kurt Russell, following 1969's The Computer Wore Tennis Shoes and 1972's Now You See Him, Now You Don't.
Dexter's science class continues to make a huge dent in Medfield College's budget with their experiments. With Dean Higgins' job on the line, he fires Professor Quigley in protest. During the kerfuffle, Dexter's experimental strength serum ends up in Schuyler's vitamin cereal experiment. After eating the cereal the next morning, Dexter discovers the cereal has given him Herculean strength. Upon seeing this, Higgins takes the opportunity to market it in an attempt to get Medfield out of the hole yet again to the company who made the cereal, Crumply Crunch, who decides to challenge their rival, Krinkle Krunch, at a weightlifting contest. Unfortunately, said rival company is in cahoots with recently-released A.J. Arno, who wants to steal the strength serum for themselves.
Tropes found in The Strongest Man in the World:
- The Alleged Car: Dean Higgins' car, to the point that in the climax, Dexter powers it up by using his strength formula in order to return to the weight-lifting competition.
- Animated Credits Opening: The opening credits for the film shows a montage of a young boy with Herculean strength performing different feats of strength.
- Arson, Murder, and Jaywalking: When Schuyler is captured by Arno and Cookie in an attempt to get him to tell them what he put in his formula, Ah Fong, an accomplice of Arno, uses Chinese techniques to get Schuyler to reveal the ingredients, which are, thymine, calcium pentothenate, niacin, pyrodoxine, pyridoxamine, and a slice of pizza.
- Balloonacy: Happens to Police Chief Blair when he accidentally runs into a balloon man's balloons while riding on the motorcycle of one of his policemen.
- Big Eater: Elmer, the student who Dean Higgins reprimands for eating in class.
- Brick Joke: After (supposedly) getting the ingredients for the strength formula from Schuyler, Mr. Krinkle puts this to the test by karate chopping the table, only to break his hand. This occurs again at the very end of the film.
- Chuck Cunningham Syndrome: Henry Fathington, who was a central character in the first two films, does not appear in the film, and nor does Dean Higgins' rival, Dean Collingsgood.
- Corrupt Corporate Executive: Kerwood Krinkle, the president of the Krinkle Krunch cereal company.
- Demoted to Dragon: A.J. Arno, who was previously the Big Bad of the first two films, is now The Dragon to Harry, though in this case, Arno is more of a Dragon-in-Chief.
- Dropped Glasses: Happens to Dean Higgins for a few seconds when trying to clean his glasses when they get fogged up after he eats some of the strength formula-laced cereal during his demonstration to the board at the Crumply Crunch company.
- Everything's Better with Cows: Ruthy-Bell, though only at the beginning of the film.
- Exact Words: After Arno and Cookie are given the assignment to steal the strength formula from the college, Arno tries to assure Cookie by telling him "You do the leading and I'll do the following". He later regrets this decision after he and Cookie attempt to pull of the heist.
- Fingertip Drug Analysis: Dexter does this after finding the vial containing his strength formula at the science lab, which is needed to win the weight-lifting competition between Medfield and State. He is able to identify it by its distinctive acid taste.
- Honest Corporate Executive: Harriet Crumply, as a female example of the trope.
- Impact Silhouette: Arno and Cookie land on the pavement of the sidewalk after falling off the scaffolding when they try to escape, and when the security guards come to the window, they only see the impressions of the two crooks in the sidewalk.
- Ironic Name: Brutus, Schuyler's dog, who is actually a cute fuzzy little dog who lacks courage.
- Malicious Misnaming: Mr. Krinkle calls Dean Higgins "Wiggins" when taunting him about the weight-lifting competition.
- The Mole: Harry, an employee at the Crumply Crunch company, turns out to be this for the Krinkle Krunch company.
- Pintsized Powerhouse: Brutus, Schuyler's dog, becomes one after eating the leftover cereal that Dexter had started out on, which causes him to start chasing after Blossom, the Doberman who had been bullying him.
- Police are Useless: The policewoman who Dean Higgins tries calling on the phone to report the kidnapping of Richard Schuyler insists that a boy being kidnapped while out looking for his dog is not unusual.
- Stock Scream: When Arno and Cookie are trying to escape from the school science lab after being discovered by the security guards and they end up falling off the scaffolding, the infamous Goofy holler can be heard as they're falling.
- Super Strength: Enough said.
- Taking You with Me: A corporate example. Upon learning that he's being fired for allegedly mismanaging Medfield's science funds, Dean Higgins proceeds to fire Professor Quigley since his students' experiments are the reason for the financial hemorrhage.
- Title Drop: "Dexter Riley's the strongest man in the world!"
- Watch the Paint Job: Dean Higgins is highly protective of his car, and he becomes very worried when it gets destroyed after Dexter drives it back to the competition after giving it some of his strength formula to power it up.
- World's Strongest Man: Dexter inadvertently becomes this after eating Schuyler's cereal, in which Dexter's formula landed in.
