Julius and Vincent Benedict are the results of an experiment that would allow for the perfect child. Julius was planned and grows to athletic proportions. Vincent is an accident and is somewhat smaller in stature. Vincent is placed in an orphanage while Julius is taken to a south seas island and raised by philosophers. Vincent becomes the ultimate low life and is about to be killed by loan sharks.
Acting
Schwarzenegger's comic timing is genuinely disarming.
Writing
The 'leftover genetic garbage' premise is unhinged science.

Director
Ivan Reitman
Trivia, insights & behind the scenes
Schwarzenegger and DeVito both took zero salary upfront, instead earning 20% of the box office — they made $35 million each when it became a smash hit.
This film basically invented the 'unlikely twins' genre that dominated 90s comedy, and Reitman only got it greenlit by promising a cheap $18M budget.
