L'uomo più forte del mondo

Third and final time Cesar Romero played the character A.J. Arno in a Disney film.

In the very last scene, Phil Silvers does a karate chop on the cereal table at the weight contest. A split second before he "chops" the table, he turns his hand downward and instead slaps the table. They try to hide this with a cereal box, but you can still see the error.

After Dexter Riley lifted the 1111 pound barbell, as Medfield College defeated State College Phil Silvers's character, Kirwood Krinkle, left the Medfield team celebrating and in another room he tried a karate chop on a metal statue. As soon as his hand hits the statue, filming stops. Then he appears in extreme pain, mouth wide open as if screaming OUCH! With his open mouth and still photograph, the words "The End" appear, after which the closing credits begin.
