The Strongest Man in the World is a 1975 American science fiction comedy film directed by Vincent McEveety, produced by Walt Disney Productions, and starring Kurt Russell, Joe Flynn (in his first of two posthumous roles) and Eve Arden.

Medfield College's Dean Higgins is about to be fired for financial mismanagement due to extreme overspending by Prof. Quigley's science class.

Higgins finds out the high costs are for renting a cow as a test subject; they are feeding it various concoctions to make it fatter.

Dexter shows the dean and Quigley his super-strength by picking up an obese kid in a chair with the right hand and Schuyler with the left.

On the day of the competition, Dexter realizes it was his formula that gave the cereal super-strength; he sets off to the lab to get it, taking the Dean's beautiful but slow vintage car.

Vincent Canby of The New York Times described it as "a Walt Disney comedy based on the old magic-formula story that's served the company well through thick (The Absent-Minded Professor) and thin (The Computer Wore Tennis Shoes).

[2] Stuart Oldham of Variety remarked that "the students of Medfield College unintentionally zap the laws of nature with unexpected and sometimes hilarious results".
